Need a good Anime to overcome my Depression

one piece makes me laugh af, i recomend

Slime Rimuru Tempest Best Anime!

I don't watch anime, just never got into it, and I'm not depressed, so maybe you could try doing something productive with your life

Yeah attack on titan my dude.

Fruits Basket its super lovely and light. Also not an anime but Steven Universe helped me when I was going through very bad periods of my depression

One Piece/Sono Bisque Doll wa Koi wo Suru
if you need short animes watch one piece or you want long animes you can watcj naruto jjk

Ifyou like comedy try to watch Grand Blue
