Hi and welcome Animal
Could be PAWs - you can check to see if this link rings any bells..
PAWS | Digital Dharma
But honestly I think when you *know* it's time to change, and you have to say goodbye to a major part of your life (even if that part is kinda dysfunctional) it leaves a hole..and it leaves us a little depressed.
Give yourself time - start building a new sober life...use all the support you have - a few months from now you won't know yourself Animal
