I am a retired school teacher and have been married for 28 years. I have two children, a son who is 24 and a daughter who is 15. I am a Vietnam veteran who is 80% disabled. I have read that PD can be caused by exposure to herbicides and I was exposed to Agent Orange. My main problem is balance, but I do suffer from chronic tiredness and weakness. I am able to work a part-time job two or three days a week. I have some other severe health problems. I get frustrated because people tell me how good I look, but they can't see or feel what is going on inside of me. I feel very much alone!
