Perhaps if it gets to be too much, my therapist advised me to go in my room, shut the door, and SCREAM into my pillow -- then start pounding the pillow as hard as I could. I could keep doing this until i was exhausted. This helped to get rid of some of the anger at the moment. And it really worked!!
You might ask YOUR therapist about this. He/she might not agree with this type of activity, but it sure worked for me.
I wish you the very best. Keep us posted on your progress, ok? God bless. Hugs, Lee
