Hi Marty. I've experienced the pain and disappointment of relapse, it's the pits I know. But never give up hope. Plenty here have gone on from that to lead happy sober lives.
AA worked for me. Being around other alcoholics was such a help. When you go tell them you're a newcomer and accept help when it's offered.
But please get yourself checked over by a doctor. They may be able to help with the worst of the withdrawals.
Hang in there x
