Got called a "piece of shit" by a family member because i dont feel like doing that stupid job and want to go back to school

I know it’s not relevant, but I am 15 years old, I graduated 9th grade, and got a waitlist 2 weeks ago. I asked some of my family members a week ago and they told me to get a job to make them happy. I got a job in like 2 days and have been working at it for a week now. Today I asked them and they got mad and said "Are you a fucking idiot? Why the fuck do you keep asking, you already have a job! Are you a piece of shit? Shut the fuck up!" and just started screaming at me. I know the answer to the hate shouldn’t be more hate, but what am I supposed to do? I want to go to school, I hate this job, and my life is borderline meaningless.
