I think Mary Jane might be a good option. The MC is a psychologist. Though in my personal opinion things mostly indirectly happen to the MC until in later chapters. I mainly stay because the story line is actually good.
Missing Love, Mary Jane, Love History, The pawns revenge, dark fall, and Profundis.
The mcs can’t catch a break fr.
Interview with a murderer and stuff that Team S&S makes, like Moritat and Radio Storm.
The beast must die
'Psycho'(young dream)
'Interview with a murderer'
'Checkmate'
'Similar terms'-- this one might be a bit weird read tho haha
If youre okay with not bl then try this

Looking for a good psychological. Not one that's just shock value and "let's see how many crappy things we can throw at our mc" but like, something that's a little more complex I guess? Idealy "BL"
