Am I being dramatic about my work load?

The school years started up again and my parents pushed for dual enrollment, so I decided to enroll in some college classes online. They want me to have my associates by the time I graduate high school. I'm also in AP classes, which gives me a lot of homework. I get up at 6am and leave for school around 7am, I get home around 4pm. I have to take these classes on top of my job, usually I'm scheduled 5-10pm on school nights and get home around 10:30, then do homework till 11:30, and take a shower and go to bed. I also work weekends and have home work weekends. I already have my scholar designations but have to take ap calc and ap lit.

My parents have recently been pushing for me to volunteer, which I agree I should, but I've already been feeling extremely stressed with my current workload, which I tried explaining however I was told that my cousin is working and only has to take one class this year, and he's in sports (they also are pushing for me to do sports).

I know I should be able to handle it, a lot of people handle more, but I've just been feeling so burnt out. I don't have much time for myself, and don't sleep a lot due to getting in bed late and having trouble sleeping involving sleep paralysis.

I have to do this while my sibling is going to college, which my parents are completely paying for even though she failed her SAT and graduated with a low GPA, never took dual enrollment, ap, or honors. I plan on joining the Navy and getting a engineering degree through them. I know she needs extra help since she doesn't like studying, so it feels wrong to be jealous, but I hate to admit I'm a bit angry about it.

Sorry about the rant, please be honest and let me know what you think.
