I had this onset a couple of years ago, at 43. I didn't even realize it until a co-worker shut the door to my office and asked me what was wrong. The shortcut to the end - I saw my doctor and he gave me a list of suggestions that I took to heart. Now I exercise religiously (seratonin booster), do something for ME every couple of days (stress reliever), try to be outside for a couple of hours every couple of days (seratonin booster, fresh air, vitamins D/K enhancer), and stick to a regular sleep schedule... I'm a whole new person. If that didn't work he was going to give me an anti-anxiety pill, but I haven't needed it.
