Your third paragraph says it all - you know where the 'comforting' drink would lead. Nothing gets accomplished when we numb ourselves to get through the rough times. We don't come up with any solutions or learn anything - we just put everything on hold.
As Dee said - there's nothing wrong with you. I had the same feelings when I was newly quit. I had to learn all over again how to deal with life, without my 'buffer'. It's not our friend. It keeps us down and unable to move forward. You are going to feel much better as you go along - we're here to listen and help. You aren't alone.
