I think that some of what your T said is fact, there is definitely an importance to apply radical acceptance where it's needed......but also, you need to define what is causing you to feel angry. Where is that emotion coming from? You need to process those things so you can start to let them go......& even radical acceptance is a process that we have to do over & over on some things before we can get them to the point we can deal with them in an acceptance way.

When I finally left my husband 5 years ago, I was filled with anger at everything in my life......When I think about the things that caused the anger in my life (from my husband to my mother whose choices when she was dying caused me to go through a horrible trauma), I still can understand why I felt the level of anger I did, but I have been able to process what happened & have accepted that what happened happened & there is nothing that I can do to change or fix any of it.

Any time I have any dealings with my husband, my level of dislike for him rises again but since I don't have to live around him 24/7 any longer, my level of irritation comes down very quickly. I realized that I was like that full glass of water that is bulging but not overflowing (that water was my anger) & one drop more would just send me into overflow.

My anger came from being lied to continually whether openly or by things left not said. His financially not taking care of the family. My anger toward him started even before we got married & he didn't do anything to fix those things that kept hurting me, causing me stress & making me feel like he really didn't care. When you are able to understand better what is causing the anger, then you can deal with it better & it does become more than just accepting the things it's more about understanding. I don't believe even with the radical acceptance that DBT calls for that it can be done without understanding.
