I'm glad you mentioned sorrow, because I heard a lot of grief in your post. What I've learned from my experiences is that grief, like all other things, will need to be felt fully and dealt with, then it passes. Dealing with grief SUCKS. You're doing it, every single day you stay sober. It may not seem like much right now, but you will be amazed when you start to come out of this... and you will come out of this.
There is no always/never/forever, life is ever changing, sometimes breath by breath. Give yourself time to feel whatever you need to. You've obviously got enough faith to do so, otherwise you wouldn't have posted here. So, feel it and keep on trudgin - you'll get to use this experience to help someone else down the road.
Big major rib crackin hugs, buddy.
