My brother bought me a flight to visit him and his family around Christmas in Las Vegas. My migraines are changing again, and I'm getting nausea and headaches and confusion. I'd gladly pay for the cost of the ticket, but feel bad if I should back out of the visits. Don't know what I should do; I feel he'll judge me and be disappointed and possibly not understand. And then again I could be wrong he might understand and maybe it doesn't matter what he thinks. I'm afraid the long flight is going to trigger a migraine.
