Hi, and welcome!
Not to put too fine a point on it, but your girlfriend is a total mess, and she's dragging you down with her. She is physically and emotionally abusing you, and her intoxication/addiction is no excuse.
I understand that you care about her, but you CAN'T "recorrect this whole thing." The only one with the power to help your girlfriend is herself, and if she doesn't respect or care about herself or you enough to get help, there is nothing you can do to change that.
You're a young guy, and you are throwing your life away. I'd suggest letting go and moving on. This is not a safe or healthy situation for you--and it's not doing her any good, either.
