Aside from generic symptomology, how do you know if you're hypomanic or elevated?

Since Friday, I keep feeling like I need to keep talking even though I don't really feel like talking. My mind keeps going from one thing to another and I keep forgetting what I'm doing as a result, unless I repeat the task I'm supposed to be completing in my head, or try to keep reminding myself of it. I'm becoming oversensitive and a little agitated. I've been pretty productive but more frequently finding it hard to focus. I feel great and awful all at once. I feel more creative, wittier, able to form insightful connections in my head between unrelated things. I'm afraid the wrong thing could come out of my mouth at any moment in response to anything, because even the bad things I might say don't seem to be that bad. More impulsive. Reactionary to stupid, meaningless things.

Not asking for a diagnosis, but if anyone can identify with any of this, I'd like to know. I'm sorry if this is a bunch of babble, but if I don't get it out as it comes, it disappears and I might forget.

Aside from all this, what are some things unique to you that are potential red flags that you might be elevated or hypomanic?
