There are some symptoms of BP disorder that for a long time I didn't identify with, like spending sprees, (although, I am 15, and I don't get allowance, so spending sprees aren't possible for me) increased sexuality, ( I'm pretty much normal all the time, I don't all of the sudden go sex crazy) and rapid thinking.
Although, I'm not so sure on the rapid thinking any more.
What happens to me, during any and all moods, is that I'll over analyze the simplest thing.
LIke,
The other day I was walking to class, and a girl on crutches was coming through the doors, I had to stop, and wait for her to go through. I glanced at her, and smiled, the normal casual greeting.
Then, my mind went into overdrive.
I started thinking "you're not supposed to look at people who are disabled! Did I look at her too long? Would I have smiled if she weren't on crutches?" blah blah, until the "I'm over analyzing this" thought kicked in, Then I tried to stop, and clear my mind of the whole thing, and I try to pause the thoughts, but more keep coming through. "well, shes only on crutches, she's not perm. disabled." and a million reasons why its not a big deal. I keep trying to pause my mind, and more thoughts ram through.
A small thing that wouldn't normally even register more then a "let me wait for her to go through" in my head, turned into a 10 minute long thinking fest. This normally doesn't happen more then 3 times a day, and has happened while i was in a "depressed" mood, although Its more common in normal or manic moods.
Is this what racing thinking is like for you?
