The first time I learned of my husband's claustrophobia was about 20 years ago. We had been camping in a small trailer that had foil across the back window where the bed was located. Don was sleeping on the inside of the bed, near the back wall, and I was sleeping on the outside so I could get up and down easily with the kids, or to pee, but that's irrelevant. The point is, Don woke up during the night and couldn't see a thing. It was pitch black and he darn near killed me as he climbed on and over my sleeping body to get out.
A few years ago, we learned that Don has Relapsing Multiple Sclerosis. His neurologist wanted to see if the MS has progressed or stayed the same, so she ordered an MRI last week. I am quite amazed that he was even able to get in that machine!
