My mom pisses me off!

I'm fuckinh sick of my family! My mom is being a fucking bitch! I wanted to go see my boyfriend today. I've been cooped up in the house the past two weeks with nothing to do because he's been doing work in another state. Plus my 25th birthday is coming up and he will be leaving for work again soon and I want to do something before he has to leave again. But no! My mom wouldn't let me take her other car because she wanted me to watch my half brother. Who is 16! My mom started working a second job because of money issues so she hasn't had time to be home a lot. My half brother is on "suicide watch". Mom had to take off work last week because he was cutting himself. Honestly that shit was such a cry for attention and now he's got it and my life has to be miserable. She wanted me to watch him and make sure he didn't stay in his room all day and talk to him. I stayed home. That's all I did. He stayed in his room. I wasn't feeding into his cry for attention and then my mom gets mad at me for not checking on him. I told her she can just quit that second job and be home with her son and she says we need the money and blah blah blah. We've also had issues with the chores. Me and my half brother were supposed to switch off on dish night but she's making me do the dishes this whole week because he's fucking mopy and she wants to give him a break until he sees a therapist next week. I'm about to just not do anything around the house because I'm still pissed I couldn't see my boyfriend. I don't care of the house gets messy and my half brother isn't my responsibility. Nobody told her to work 65-70 hours a week. If I was working I would never work that many hours. Honestly to some this may not seem like a big deal but to me I'm just sick of family.
