how can i tell when im manic?

hi yall, so i’ve been diagnosed with bipolar disorder for about two years now. i really really struggle with being able to tell when im manic, even though i am medicated and have a solid support system around me. even when im told im manic i struggle to believe it until i come down on my own. does anyone have any tips for how they realize they’re manic or how to pull myself out of a manic episode? i can’t handle the months of overspending, impulsive decisions, no sleep, and being a nuisance to the people around me. please help!!
