I know I say this a lot here, but EMDR helps me. I find it very relaxing - usually.
I once tried Krav Maga and probably would have continued if the instructor hadn't moved his studio thirty miles away, but the two times I went were awesome. If nothing else, you'll be too exhausted to do anything but relax.
I'm going to look into the TRE thing Teacake keeps mentioning. Surely even the public library in a hick town in the middle of Oklahoma can get David Bercelis' book since we don't have a BOOKSTORE. Jeez!
