I did let the anger consume me. The anger would make me feel better in the moment because I didn't want to deal with the primary emotion that was causing the anger. The anger gave me a false sense of control. The main reason I was angry with God was because I felt he had abandoned me, not just finding a job but in my life in general. People (including my W) would always tell me to pray for a job and God would open doors. It might be a stretch but when you are angry you don't think rationally (at least in my case).
I have read about 100 pages of DR. I am making progress in changing myself. Yes, I have been angry with my MIL for a long time. I am working on that issue.
