Have you looked into an outpatient program? Since you work, you must have some kind of insurance.
I had nothing legally happen to me with my drinking but my boyfriend was tired of it, it was ruining my relationship, I hated going to work, I didn't lilke AA. Outpatient forces you to be sober and to be completely honest. You are also required to go to meetings. It's a lot of work but it may be the thing that saves you.
If you put energy into getting better, then your girlfriend may take you back. If not, then at least you are doing this for yourself.
At least see what your insurance says. Go see your primary doctor and be completely honest. The beginning stages of recovery absolutely suck and most days I want to throw in the towel. But I am so glad that I am doing this at age 30 instead of 10, 20, 30 years later. Think of the life you can make for yourself once you get over this hurdle.
