Good advice. Thanks @becsbuddy the logic behind the "worst case scenario" is a real good "tool" that I use often, but I struggle to apply it while in my "summertime hibernation" mode. I guess one "worst case" is that the Rheumy tells me that she has never heard of someone who has to hibernate during the summer. Apparently, I have both heat and light sensitivity. When the summer hits, I shut-down and hibernate and have since my youth. The light sensitivity only began since retirement and I have to wear sunglasses in the house to avoid glints of light from the windows or I get blind spots and migraines. It only happens certain times of the year though, I think according to the sun's angle. I have begun to read of other people with similar symptoms (maybe). I want to ask her, if that is what people mean by sensitive to sun. I guess her answer won't kill me, either way-but maybe an undiagnosed and untreated disease can.
