I was thinking along the same lines. My mom self medicates with alcohol. She's been an alcoholic as long as I can remember... When drinking, she's pretty happy and talkative. However, separate her from alcohol for 3+ days and she suddenly becomes very explosive.

That's why it's so hard to figure things out when any kind of substance is in the equation...

It bothers me when people blame their behavior on a disorder. Regardless of what I'm told, I will NEVER blame my behavior on one. I can get a bit snippy with people I care about. I feel bad about it later, almost all the time. I think many of us here would agree.

Whatever is going on with this girl, she sounds like she does need some help. Even if it is merely a result of her dependency to alcohol, that alone would warrant needing help.

She sounds very much like me when I was 13-15, to be honest.
