I am way way older than you are. I went through episodes like that multiple times. There was always a trigger, work related or personal.

This is depression. Seek medical help. Find a good therapist to talk you. Get 10-15 sessions. Find the root of the problems. But the most important thing to do is talk. Don't go to social media, HN, or whatever. Bars, concerts are to be avoided. When you are there you'll get the feeling that you don't belong.

Medication can also help on a temporary basis until you find that you can get back feelings you had in your 20's.

The worst thing you can do is nothing. It will not go away. If it does, it will come back.

I guarantee that after you seek medical help and handle that with a therapist you will gradually feel more excited about life, there are so many wonderful things to do, experience and good people to meet.

Good luck.
