Hey nie, sounds like we're in the same boat. I have been noticing a lot of anger surfacing recently. It's definitely not a feeling I'm comfortable with and I usually try to avoid it. The thoughts that have crossed my mind have shocked me at times and these thoughts often lead to anxiety.
My therapist helped me a lot with this one. She assured me that just because angry thoughts might be frightful/violent/bizarre, it does not mean we are going to act on them. No matter what angry thoughts come up, we can control our behaviour (e.g. go for a walk, punch a pillow, etc). For me, this was very comforting. Also, my therapist told me that it can be liberating to 'fantasize' with our anger. She used the example of visualizing myself beating up my past abuser in order to release my angry feelings. Of course this is just fantasy, and as long as we can differentiate between the two it can serve as a good release. I have yet to become really comfortable with this idea, but it might work for some people. I just went and read the rage/anger thread and realized that this 'fantasy' exercise might not be the greatest for everyone. I just thought I would pass on what my T suggested for me :)
I'm curious to see what other people have to contribute in this thread...
