Why Can't I Feel Happy Anymore? Causes of Emotional Numbness

If you can't feel happy anymore, you may be experiencing anhedonia: a loss of pleasure or interest in things you used to enjoy. It is not a condition on its own. It is usually a symptom of something treatable, such as depression, bipolar disorder, trauma, or a medication side effect. A psychiatric evaluation can sort out which.

Have you ever felt like nothing excites you anymore?

Maybe your favorite food tastes flat, the music you love doesn't reach you, or plans with friends start to feel like chores. Everything may look fine from the outside, yet nothing feels enjoyable the way it used to.

If that sounds familiar, you're not imagining it, and it isn't a lack of gratitude or effort. This inability to be happy is common in depression: somewhere between a third and two-thirds of people with depression have it, depending on how it's measured.

What is anhedonia, and is it the same as emotional numbness?

Anhedonia (an-hee-DOH-nee-uh) is a reduced ability to feel interest or pleasure in things that used to matter to you. Doctors describe it as "markedly diminished interest or pleasure" in almost all activities. It's one of the two core symptoms of depression; the other is a depressed mood. Only one of the two has to be present. This is why some people with depression don't feel particularly sad; instead, they describe feeling flat or empty.

Although many people use the words anhedonia and emotional numbness interchangeably, they are not the same. Anhedonia is mainly a loss of pleasure and interest. Emotional numbness, which doctors often call emotional blunting, narrows feelings in both directions: less joy, but also less sadness, worry, or ability to cry.

Knowing the difference between the two is important because blunting is sometimes related to antidepressant treatment, which your prescriber can review. In one survey of 669 people with depression taking a single antidepressant, 46% reported emotional blunting. However, blunting was not simply a medication side effect. It was more common in people who still had more depression symptoms, which suggests that both the illness and the medication can play a part.

If you're taking an antidepressant and this sounds like you, contact your prescriber. Don't stop the medication on your own. Sometimes an adjustment, rather than stopping the medication, is more appropriate.

What are the two sides of anhedonia?

Researchers split anhedonia into two parts:

• Anticipatory anhedonia is losing the wanting. You stop looking forward to things, and it gets hard to start them.
• Consummatory anhedonia is losing the enjoying. You do the thing, and it doesn't feel the way it used to.

The wanting side is tied more closely to dopamine, a brain chemical involved in motivation and reward.

Why do I feel this way?

Anhedonia is usually a symptom of an underlying condition. Besides depression, possible causes include:

• Bipolar disorder. Loss of interest in almost all activities is also a symptom of the depressive episodes of bipolar disorder.
• Trauma and PTSD. The diagnostic criteria for post-traumatic stress disorder (PTSD) include a persistent inability to feel positive emotions, such as happiness.
• Long-term stress. Researchers think that prolonged stress may dampen the brain's reward system, which is one proposed route to anhedonia.
• Difficult early experiences. Childhood maltreatment and neglect are linked to lower motivation and weaker responses to reward in young people, and to a higher lifetime risk of mood and anxiety disorders. A higher risk, however, is not the same as a certain outcome.
• Other medical and neurological conditions. Loss of pleasure and motivation also appears in a range of other psychiatric and neurological illnesses, which is one reason a thorough evaluation is worthwhile.

How does a clinician find the cause?

When someone says they are not feeling happy anymore, the first thing a clinician wants to know is that they are safe and are not having thoughts of hurting themselves. Clinicians ask everyone this question directly. It is a routine part of every evaluation, and an honest answer helps guide the right next step.

After that, the clinician's best tool is a good history: how long the person has felt this way, what was happening when it started, how severe it is, and what else has changed, such as sleep, appetite, energy, and concentration.

Then the clinician looks for immediate causes that can be pinpointed and fixed. A recent medication change is one example, because some antidepressants can cause emotional blunting, which people sometimes confuse with anhedonia. A useful question is whether the person can still cry or feel upset: blunting dulls both good and bad feelings, while anhedonia mainly affects pleasure and interest. Alcohol or cannabis use and medical issues are checked too, including recent lab work, thyroid problems, and sleep problems such as sleep apnea (repeated pauses in breathing during sleep).

Next, the clinician considers conditions other than depression, such as bipolar disorder, by asking about past periods of highs known as mania or hypomania. These are stretches of unusually elevated mood and energy, and hypomania is the milder form. Deeper, long-standing issues, such as a history of trauma or neglect, may also contribute. Treatment is then guided by everything this history uncovers.

Why does anhedonia matter?

Anhedonia matters for treatment. When loss of interest and enjoyment is a prominent part of someone's depression, a first antidepressant tends to work less well. Treatment may then need to be adjusted, added to, or changed. This is one reason to describe this symptom specifically to your doctor, rather than only saying that you feel depressed.

Anhedonia is also linked to suicidal thoughts, even after accounting for how severe a person's depression is. This link does not mean that everyone with anhedonia is at risk, but it is a reason to discuss the symptom openly with a clinician.

How can I feel joy again?

When you are living with anhedonia, it can color how you see everything, including the future. Many people start to feel that this is it, and that the feeling is permanent. That belief is understandable, but it is not accurate. Anhedonia is a symptom, and although it can be hard to treat, it often improves.

Treating what's behind it

Because anhedonia is a symptom, treatment focuses on the condition behind it. If the cause is bipolar disorder, trauma, or a medication effect, treatment is tailored to that. For depression, no treatment works for everyone, and options are often combined. The main options include:

• Medication. Loss of pleasure often improves as the depression improves. No single medication has been shown to be clearly better for it, and it can be one of the harder symptoms to shift.
• Therapy. Behavioral activation, a therapy that gradually brings meaningful activities back into your week, has been shown to help depression. Studies suggest that both therapy and medication have a modest effect on anhedonia specifically.
• Exercise. Exercise can be an effective treatment for depression. In a large review, walking or jogging, yoga, and strength training did best. It can be used alongside therapy and medication.
• TMS (transcranial magnetic stimulation). TMS for depression is cleared by the FDA, the agency that authorizes medical devices, and uses magnetic pulses to stimulate the brain. When depression improves with TMS, loss of pleasure and interest may improve along with the other symptoms.

What if the joy doesn't come back right away?

In my experience, when anhedonia is part of major depression, it often takes longer to improve than the other symptoms. Sometimes it requires additional steps, such as adding a different type of antidepressant, adding an adjunct medication (a medicine used alongside an antidepressant to strengthen its effect), adding therapy, or considering TMS. Depressive episodes of bipolar disorder follow a different treatment approach, which is another reason an accurate diagnosis matters.

The next step is an individual decision, and a fixed, one-size-fits-all sequence would oversimplify it. Every person takes a slightly different path to recovery. That is why it is important to tell your doctor when enjoyment hasn't returned, even when you have improved overall.

Frequently asked questions

What should I do when nothing makes me happy anymore? Start by talking with a doctor or psychiatrist, and describe the loss of enjoyment specifically rather than only saying your mood is low. If you take an antidepressant, contact your prescriber instead of stopping it on your own. Try to keep some activities in your week even before they feel rewarding again, which is the idea behind behavioral activation. If you have thoughts of ending your life, call or text 988.

Is it normal to not feel happy? Everyone goes through stretches when life feels flat, especially during stress or grief. It is worth a closer look when the loss of pleasure is present most of the time, lasts for weeks, and starts to affect your work, relationships, or daily routine. At that point it may be a symptom of a treatable condition such as depression, and an evaluation can help find the cause.

Will I ever be happy again? Anhedonia often improves once the condition behind it is treated, although in my experience it can be one of the slower symptoms to recover. It can help to watch for small changes, such as enjoying a meal again or looking forward to a plan, and to tell your doctor when enjoyment is still missing, because that helps guide the next step in treatment.

Where should I start?

A good first step is a free depression screening, which gives you a starting point for a conversation with a clinician.

Before an appointment, it can help to write down a few things. Note when the loss of enjoyment started and what else has changed in your sleep, appetite, energy, or concentration. List any medications you have started or changed recently, and anything you have tried that has or hasn't helped. These are the same questions a psychiatrist will ask, and having the answers ready makes the evaluation more useful.

If the flatness has lasted for weeks or is affecting your daily life, a psychiatric evaluation can help find the cause and guide treatment.
