Bama,
There are ALWAYS options. Yes, rehab would be nice but it is not necessary in order to clean-up. Millions manage to get clean and sober without rehab. I think you know that. You can call friends in NA; you can check yourself into a hospital for detox and follow up by going to a SoberHouse. You can go hang at meetings all day. You can decide that you cant fight it and give it to God. I know as long as I tried to fight it it didnt work. I'm not saying it is easy but i am saying its possible. If you want it as bad as you say you do you will find a way. I did. So did others on this board. You can too.
My thoughts and prayers are with you....
