You mentioned going back to school, but without a direction to go in, why not wait, a little while, until you know. Being a bartender, must have a positive aspect? You need some good personality traits to do that! My Mom was one, for many years, outgoing, friendly, good listener, trustworthy, and more...
I can't picture bartenders, anything but those qualities.
21 is still very young, so you aren't into politics, big flying whoop. Not everyone is, doesn't mean you can't think for yourself, formulate your own opinions.
My Mom met my late stepdad, through work. He was good to her, she was good to him.

Hang in there
