Don I will address reason 1. I also hit the wall with high blood pressure. Mine was , and I will always remember the number, was 249/125. This caused a fairly massive stroke. It was on January 1,2017 just to start that year off with a bang. I am on my meds now and my blood pressure is now in the normal range. This forced me to retire from officiating football after 18 years. You can't officiat a football game if you can't run.
Hope you get better and get back on the field when you can.
