finished school yet bpd is ruiining my life

A gf of of 7 months has been acting like a cunt for the past 3 and now instead of admitting and apologizing with a meaning shes (which would have first of all eliminate the black and white thinking subconsciously not me paranoid thinking and stuff which is greatly justified ) decided to fuck me so mentally that ill leave her and u dont know i gave my everything for her reputation , status, friends but not in a way that she would be a bitch but she became my fp and i subconsciously pushed everybody away and now it ended like it always ends EVERYBODY HATING ME i acted the way i acted because she gave no reaction at all so now i look like an idiot in everyboys eyes

idk for part 2 not even sure abt part one
