Her sister also said she was 100% sober the whole time she was hanging out with the wiggers, which is just blatantly false. Sure, the zoloft probably pushed her over the edge into "actually going to act on suicidal impulses" territory but getting mad fucked up with a bunch of drug addicts 10y older than her and then told "actually fuck it, go to college, i got new whores flying in lmao" after Jet's whole spiel about how college is a scam and he'd totally give her an internship on future Fishtank projects definitely didn't help.
It is quite literally the exact same shit jet did to Ciara, where he isolated her from her simps and then became her sole drug-provider, hit it, and ditched her when she actually wanted a relationship. Dudes who fuck with young easily-exploited girls are just scumbags.
