I would caution against calling it depression, which is a set of symptoms classified as a disease and really can only be evaluated by a professional.<p>However, I recently went through a period of anhedonia (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Anhedonia" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Anhedonia</a>), which may be what OP is experiencing.<p>Things that I found that worked: exercise for pleasure (riding my bike!).  Connecting with people (one-on-one -- i&#x27;d always been part of a big group before).  Learning new things, new challenges.  Yoga.<p>A book that helped me a lot was Frankl&#x27;s &quot;A man&#x27;s search for meaning&quot;.  I realized that I had a bit of fight club nihilism in me because I never chose my purpose in life, and so was just sitting on the metaphorical treadmill of existentialistic wallowing.
