i usually read. https://www.mangago.zone/read-manga/murderer_llewellyn_s_enchanting_dinner_invitation/. but that's depressing so maybe try reading https://www.mangago.zone/read-manga/our_sunny_days/.
I don't know about you but when I feel low, I like to read traumatic/depressing works.
But read these, it's cute and might make you feel better:

Mangas you read when you're depressed? I just can't bring myself to look for mangas to make me feel something. I feel so empty and I feel like it's too much. Life's just too much for me right now.
