I tried to quit for ten years so I know how you feel. I felt like you do now every day for ten years.
You can make it through this. You're not a loser. You're someone with a problem. A problem that can be solved.
Just stop drinking now. For today.
I know you feel alone and scared, but these feelings will pass, believe it or not. And I know it was hard for me to believe when I was in the misted of it all.
Just hang in there and don't take a drink. Post here. Go to an AA meeting. Get some sleep. Do whatever it takes.
Reach down inside you and know you are loved by the universe and it, and we, need you.
Best to you, and we're all here for you.
