NeatFreak,
your description is classic symptomology of an elevated mood. You are on the high side. It may be that you need an increase in the dosage of what meds you are taking. That should be discussed with your medication provider.

When I am elevated, my concentration is very short, I talk rapidly, I tend to be obsessive, (like excessive repetition of the same thought.) It literally wears me out and I get very tired of it and start seeking a way to get down, yet avoid a crash. (Fall into devastating depression.)

For me, the solution starts when I realize I'm elevated. I become mindful of my behavior then I make sure I am taking my meds correctly. I'll take more of a drug that knocks me down. I make it a slow process so I don't crash. I remember how wonderful the last depression was. lol
