I'll pipe up...my T also suggested a self-defense class after I had done some basic trauma processing but was stuck in the freeze response. I had always wanted to try a martial art, but assumed I couldn't.

Now I've been going for a year! I love it. It has been a difficult thing at times, and sometimes I think of it as my second weekly T session because it can bring up intense emotions. But I feel stronger. It's not that I think I could take on a big attacker, but I just feel a little bit more able to set a boundary, especially verbally. It's funny--my T has been urging me to "fight back" aggressively the same way yours has (when I'm alone, curse, yell inside my head, etc. at my abuser). It's taken me this long to be willing to even try it!

There are many paths to strength and personal power, and you will find your way.
