I recommend Alanon, where I found incredible support and understanding from people who have walked in my shoes. It is a program of recovery for codependents stuck in a place they want to grow from. I find resentments intolerable to have and what helps me is asking "what's MY part in this?" In my case, I picked an alcoholic and stayed much longer than I should have. Helped relieve a lot of the rage since I saw the real problem was me. I can't change an alcoholic but I can change myself. A very big hug.
