I'm not Bipolar I'm just a bad person

F20 Medically Diagnosed with Bipolar 2 Disorder last year. I'm confused if what my family said is true or not. I'm not Bipolar I'm just a bad person they said.

I'm a college student by morning and a barista at night and I just applied for another Job at a convenience store where I'll work 12am till Idunno 8am?

Staying up late and not having enough sleep is bad for my condition because it triggers my disorder, so my psychiatrist advised me to not work and take a break from college (which I deliberately shrugged off).

They said I act out a lot. I get irritated a lot and I get an intensity of Ups and a crazy intensity of lows.

I can't control anything anymore. I feel powerless. Maybe I am a bad person and saying I'm bipolar is just an excuse.
