How do you deal with the physical manifestations of stress? Each person is different.

I like to get out and walk or ride. Sometimes a good book is relaxing. Other times a few rounds of Halo or Modern Warfare multi-player does the trick.

The key is to not second guess your decisions and leave your job at the office and enjoy life. I don't personally like the medication route but each person is different and if it works it works. It sounds like the op has other issues in his past he has not dealt with which are affecting him now. Seeing a psychiatrist or a psychologist and talking through your issues sometimes will identify this source issue and solve the problem.
