i keep a little "stress test" with a list of points for each major change in my life, and when i go over the limit, i take to my bed as if i'm sick. it's well known that too much change, whether liked or disliked, can lead to illness, accident, and injury, not to mention depression and panic. here are some of the skills and coping mechanisms that have helped me, and many others. actually a good crisis line will remind you of many of them. i hope this helps:
