I have had some trouble myself with flourescent lighting but not to the extent that you describe. If you want to teach, though, you can request different lighting for your classroom but you might end up moving frequently if there are enrollment fluctuations - sometimes new teachers end up with different assignments the first few years because of this. Also, the entire school has flourescent lighting so you will still come in contact with it throughout the day. You might need to use a high SPF lotion and wear long-sleeved shirts, jackets, and pants to help you get through the day. You might need stronger meds, too, to help keep your flares in check. I used to get ill from sunlight similar to what you described but, even though my meds make me more sensitive to sunlight, I don't have much of a problem now.
I hope this helps - my prayers are with you - Audrey Ann...
