That sounds a *lot* like what I've been through and have been dealing with. When I was 4 or 5, I was afraid to go to the doctor for fear that they'd find something wrong with me. I was also petrified of running bathwater, b/c I really,t ruly believed it would overflow the tub and we'd all die.

I've gotten much better at identifying what I like to call the "crazy brain," but all that really means is that I do have the parallel tracks running in my head. The logical side says "if X doesn't pick up the phone, she's probably out at the store or something," and Crazy!Brain says, "OH MY GOD X DIED IN A CAR ACCIDENT ON HER WAY HOME FROM THE STORE."

It's taken years of therapy and a lot of medication to get me to this point, where I can identify the crazy and try to cut it off before I start spiraling.
