I haven't even come close to hitting bottom, so I'm not much help on this question. I will say that I have an addict brother who doesn't seem to have a bottom either. He's been on and off drugs for about 20 years, and just got out of jail a couple of weeks ago. I don't know what it will take for him to achieve long term sobriety, but I know that I can't do anything to help him get there. My mother has always been an enabler, so there have been many times when he wasn't allowed to reach his bottom I think.
I'm glad you're getting support for yourself. That's really the most important thing you can do at this point. I'm so sorry for what you're going through. I'll be praying for you!
