Sure, there may be some benefit to anxiety — it keeps me on guard. But it also wrecks my sleep and has, at times, led to $1,500 Emergency Department bills that I’ve then paid by selling off cherished belongings, because anxiety convinced me that mouse droppings in my apartment meant I had contracted Hantavirus. Doctor Google did not quiet my anxiety brain down, so I drove myself to the ER at two in the morning, only to have a visit with a disgruntled doctor who didn’t understand why I was there and to be sent home with a hefty bill I spent the next year paying off.
