I know why I get HA sometimes. I mean if I have a legitimate symptom or what I think is a symptom, that can send me into a spiral. Or, if I read a story about someone with an illness that can send me into a tailspin. Or, like, right now, I have an employee whose partner is living with ALS and that has definitely sent me questioning a disease I never really thought about, but now is part of my HA. But, sometimes, with no reason at all, the thoughts come.

Today I was exercising and thinking, :I feel great" and then suddenly, out of nowhere, I begin thinking about whether my husband, who is in the military, has been exposed to chemicals that can cause cancer, chiefly brain tumors, in my kids. WHY? Why does this happen? I was not watching news, listening to anything, etc. What do you do? Where does it come from? Is it a chemical imbalance?
