I was three years into a great job as a graphic designer when I became ill (at 36 yrs old). I managed to stay in that position, with the help of the ADA, for another 15 years. There were tremendous ups and downs but I had 2 daughters and was a single parent when I became ill, plus the position provided our only chance at health insurance. I am very lucky I was able to hang in there as long as I did.
I got great support from my therapist and some support from my doctor but I always used every bit of sick time and vacation time I had being ill. I even had to take medical leave several times when I got too bad to hang in there. It's lucky I was working in city government. They abide by strong ADA rules. I left in September of 2005, exactly ten years ago this month when I became unable to stay awake through an entire work day. I literally took sleep breaks in my car, setting an egg timer for my 15 minute break. I constantly felt like laying my head on my desk and giving in to sleep. It became impossible to sit in a chair at our meetings. I was too fatigued to sit up, hold my body up that long, plus my work was at a computer for long hours, causing tremendous body pain.
These things, coupled with the drama of the office, caused me to give in on my doctors advice. He said quit or die, literally. I miss my income, I miss what my retirement income would have been. It's still makes me crazy and sad to think of what Life would have been like if I had not come down with CFS and fibromyalgia. I planned my career and was succeeding. I'm sad my plans didn't pan out. I lost a fortune.
