only one coworker knows,, no one else except close family,,I have told a few that I met at work sites and I have to admit it was very liberating..but I choose very carefully and never anyone I feel will share with my company...mostly I find the ones I have told have there own mi issues,,maybe we sense it in each other...I really wish I felt I could tell everyone,, not for sympathy but just to be out from under the secrety..but not yet....to a man every one has said "you are medicated.right.." They may be sympathic but they still fear it....
