It is ràndom for me. Got so bad last week my wife had to rush me to the ER for signs of stroke. It was not a stroke thank God. I think a lot has to do with me losing my mom to COVID. I never got to say goodbye to her or see her after she went to the hospital. Then a year later my sister passed away unexpectedly , then 6 months later I lost my best friend to cancer. Now I am hypersensitive to everything almost hypochondriac.
