I can so relate to this. I am afraid my anger is starting to get a little too much now. It does give me the energy to do things to change my situation but it is completely draining me at the end of the day. I can feel all the stress/tension in my head/neck/shoulder. My therapist said - of course you will feel that anger - unless things change or I make them change, this is my body's way of telling me that things are unacceptable as is. I am struggling with detachment nowadays.
