Hey Mattcake, I'm about a week behind you in sobriety, but I can relate. I had that same moment of clarity that I am done with alcohol for good. Right now I've been sober longer than I ever have since Oct 2005 and I have no desire to drink, so there is hope.
These feelings you are having are totally normal, so just keep letting them out! That is the best piece of advice I've been given in my recovery so far: they are feelings, it is normal to feel. Just let them out and soon you will be at peace with them.
