Hey op! I just want to share with you something that happened to me a few months ago, i lost weight, i befriended some people of my age that also like anime and now i'm getting dates with random chicks in my university. My best advice is to do four things.
Rope jumping every morning
Find a hobby
Wake up early
These four things will help you to become a better person and avoid that shit ass depression, do those things and i Promise that you will become a better and happier person :D
Best of luck and success my friend.
