I stopped taking fin months ago due to mental health reasons. But now I wanna get back on

I am (m20) and I took fin with minnox for well over a year with great results. However about few months back in December I started having serious mental health problems. Derealization and depersonalization. Along with severe anxiety and depression(it’s still a challenge but I’m getting better everyday)Now all of those can be attributed to me being unemployed for 3 months at that point rarely going out and drug abuse but I still stopped the finasteride at the time just to cover all my bases because I know it can cause brain fog and things like that but I still kept using minnox. However my very subtle friends have pointed out it’s getting bad again minnox is clearly not enough and if I wanna save my hair I gotta get back on the fin. However the problem is I’m scared. I had little to no sexual side effects maybe erections are a little less common when on it but it still works just fine it’s the psychological ones I’m worried about. People on PFS boards talk about how their lives are ruined and will never be the same which is a relatable feeling when you have derealization problems it’s very scary stuff. I doubt fin had anything really to do with my big mental health scare. Do you think my fear is irrational or can finasteride actually cause severe long term negative psychological side effects?
