I couldn't get my life in order until I got rid of the bad influences in my life and surrounded myself with people who were models for the life I wanted to live.
Recovery requires a lot of changes to succeed. I call it "death" to the old life. Complete change if need be.
Your gf still drinks. You probably aren't open to the idea of leaving her for your sobriety. Let's say you stay sober and she still drinks and takes drugs. What is your post in a couple of months going to say?
I'm sober, I think my girlfriend has a drinking problem. Anyone relate?
If you return to drinking, what's going to happen to your relationship? That could end, and you'll be drinking again. So I say, do whatever it takes to stay sober, because the alternatives are worse if you don't than what you might have to do to get there.
Not an easy place to be in. Good luck.
