The first that goes to my mind is this anime movie (it has also a manga) A Silent Voice, both struggle with mental disorders.
And in this one the ml has some traumas https://www.mangago.me/read-manga/the_bond_that_ties_us/
I know a few more but in that ones they only struggle with low self-esteem, let me know if you also are searching for that
any non-bl mangas where the mc faces depression/anxiety/any mental health related things? (not suicide boy lol)
