About to snap

Every single day I have something I have to do, not including school. I’ll work like 4-5 days in a row, always at least 6-7hour shifts too. I have math tutoring late at night 2 days a week, I have to go over to my uncles house 1 day I week minimum and help with his animals, chickens, and other farm stuff, and I have to go over to my aunts house to take care of her new puppy while they’re at school (I do online). At the end of the day it leaves me little time or energy (mentally especially) to do my school work. I’m always tired, and in a bad mood and I just don’t know what to do. I have to do all these things , it’s not like I can stop any of them, even though I genuinely am about to take off in my car somewhere and drop everything. Someone help
