Post_functional, I sympathize (and identify) with your frustration over people dismissing serious chronic illnesses, but I also found your initial post confusing and misleading. While OldAdjunct can be a little more direct and abrupt than some here, I had some of the same questions after reading your first post. Your follow-up explanation that you distrusted your former employers' responses to your illness helped to clarify a bit, but I still don't understand why you feel that you deserve a slavish apology here.
I know from your other posts that you are under enormous stress right now--and I sympathize with that. I would also like to gently suggest that the tension may have left you a bit overwrought and inclined to take offense very quickly.
You're very much right. Mea culpa.
