Looking for anime or manga suggestions where

(1) protagonist has deep rooted self-hatred and anger towards himself/herself leading to depression.

(2) there should be no love interest or loved ones involved i.e not because of failed relationships or passing of loved one. The self-hate should only be because of himself

(3) the mental health, hatred and anger should get progressively worse despite his best efforts to fix himself.

(4) focus should be on psychology and depression aspect, and not on motivational or magical healing stuff.

(5) bonus points if he doesnt give up and keeps fighting.

Edit: why the downvotes? lmao
