I've never been a worrier , and never let anything bother me, but since my wife was diagnosed with early Alzheimers I have not been sleeping as well as I used to ,and now other things are preying on my mind in the middle of the night. Usually , in the morning , they don't seem as bad , and the feeling of impending doom lifts. My blood pressure is up and down ,sometimes too low and I get dizzy , and vision blurring. I'm 71 ,nearing 72. I hate getting old..
