So I know this is a meme but I wanted to say that if anyone out there, particularly younger people, finds this ringing loudly true to their own experiences, you may be experiencing medical depression. Sure you get more responsibilities as you get older and your passions change, but if you notice something feeling off about this sensation and many things you formerly enjoyed you start avoiding because forcing yourself to enjoy them just makes you feel crappy, it isn't necessarily normal.

I say this because I went through it and I didn't get help until my late 30s and I regret every day that I didn't. There is nothing wrong with asking for help, talking about it with others, and not accepting it as a "normal" part of growing up. Without help it will take a toll on your career and relationships and your health.

Reach out.
