The stabilization term does not sound familiar. My last therapy included a few sessions where the doc (my general terminology for anyone in any type of medical or therapy job) did eye movement therapy. It seemed to help somewhat, but shortly after that I went on meds and basically all of the symptoms went away.
As for relaxation - basically nothing organized. Take the dog for a walk around the lake, go to movies with the kids, video games - I tried kayaking for the first time a few weeks ago. I've actually thought about yoga, but I'm not young, I'm overweight - not flexible, and starting would be somewhat embarrassing it seems. But I do need to increase my flexibility something terrible, and the change of pace might help. My old workout routines revolved around weights and running. The anxiety over heart issues cut out my running, and the weight packed on fast.
I apologize for the delayed response, but I'm in the middle of a long training cycle at work (one day last week was 16 hours).
