I am quitting 30mg Abilify cold turkey

I am tired of this drug fucking things up for me. I was forced onto it after my suicide attempt and all it has done to me is take euphoric feelings away and keep me in depression. I only like it for being a antipsychotic. I experienced 1 case of manic psychosis and I am scared of it happening again, I gotta be honest. 

I havent taken it in 2 1/2 days, so I know I should expect withdrawal soon. Any tips? I got Bipolar 2, OCD, ADHD-C, Aspergers, PTSD (and PTSD-C), and anxiety. I know that is a lot of disorders and quitting this high of a dose is a... risk. But I just can't stand it anymore. I've been on it since December 2020. I gained 140lbs, after having gotten to 210lbs (my lowest weight in over a decade- and I am 25 years old!) and I am just sick and tired of it.

I am going to look out for symptoms and if they appear I intend to take a 1/4-1/2 of a pill depending on severity.

I want support. To be told I am doing the right thing. But I know I'm not. It's unsafe as hell, irrational, and against my psychiatrist. I just... I can't anymore.
