yeah ... it is starting to fuck with my back too. To bad as it is the one place I really clear my thoughts. Stress for me is when I just get a bit overwhelmed - mostly ADD stupid stuff. Clearing the thoughts is one place I really get it out.
This is going to sound super stupid but one of the life changing things for me was a little book I read called "Don't Sweat the Small Stuff - and it is all small stuff". That really taught me how to say "fuck it" not shit I can do about it.
I still get stressed in certain business transactions. Hate it - my stomach fucks up and I put on stupid weight then I will will come down with a cold for flue or something messed up afterwards. Only happens about every 3 yrs but I still have it.
Hate it. Don't handle it well.
