Howdy...I "liked" your comment since I can relate. Obviously, it's not an enviable situation. I felt the same thing for the entire second half of the 40 days in regards to my wife and daughter. A few weeks into the program, I realized my anger and resentment towards them were actually my biggest issues, and not the other stuff I had been thinking/journaling about prior to that. I was TERRIFIED once I started journaling about them as I found a link between problems with them making me feel "not good enough" in life. I grew scared that my anger was going to take over my consciousness and drive me away from them.
To get past it, I worked with my therapist a lot, and kept reminding myself that people need to be forgiven. Part of the treatment is being kinder to ourselves and to stop putting impossible expectations on ourselves. I realized I was doing that to them too, by getting so upset about things they had done to hurt me. Nobody's perfect and everybody makes mistakes. I also made a "Happy List" of general things that make me happy, as well as things I love about each of them. Reviewing it when I felt down was very helpful. Eventually, I just got used to being angry with them on occasion. I had always repressed that before, so feeling it was very scary at first. It just takes time to come understand it's okay.
