I can totally relate to the resentment. For me, my resentment is/was towards the closest to me. My friends and family. I felt like saying stop making a big deal about this, I can do this on my own. I'm not going to meetings, I'm not doing this, not doing that. I just felt like they did not really understand my situation.
I made the decision to dive into SR yesterday and I cannot believe the welcome and understanding that you all have given me. I may be isolating myself to get through the initial detox phases, but so far SR has been making me want to be accountable. Hope this makes sense. I'm still trying to sort things out myself and I'm newly into this, but when I read your post I understood just what you were saying. Hang in there!
