Depressed about salary

I’m a nurse, I make shit money, stand on my feet all day, my back is giving out and I’m not even 30 yet… my holiday bonus was a $200 gift card that doesn’t work…. I found out that my younger brother got nearly a $20k bonus, a huge raise, works from home, he’s in business. Literally what the fuck did I do all this studying and schooling for???? Everyone says nursing is a great job but it literally sucks. My hair is falling out and I have acne from being stressed I hate it so much. What the fuck why the fuck I want to literally end everything
