Welcome SuzyQ979
I remember when I decided to stop drinking it was like a huge weight off my shoulders. I expended a lot of effort either getting drunk being drunk or staying drunk. My world shrunk to one room and the TV, so I identify with that part of your story too.
I did not go to rehab either, so it's certainly possible to recover other ways. Some here, like me, use SR, others use face to face support like AA or some other recovery group as well. I'm not in AA but I'm sure it's not like it is in the movies - noone *has* stand up to give a speech
it's often a good idea to visit your dr as well, if you've been drinking heavily, or regualrly for a long time. Detox can sometimes be rough for some of us.
I encourage you to look around, read post, work out what might for you.
You'll find a lot of support here
Welcome!
