need to vent/help

Okay my family is going through a very stressful time. I am 18 and take online college classes. I am take overload credits to graduate early. My parents pay for everything since they want me to focus on school. It's the end of the semester and I have tons of final assignments and tests to study for. I'm super stressed. All I kee hearing from my parents is how I sit on my computer all day... from the second I get up until dinner all I do is hw. If I was taking these classes in person I would be taking over 50 hours a week of classes plus hw. Ik they are stressed since in 2 weeks we are moving out of state and have to drive for two days. I have been trying to help as much as I can but I have failed classes before and don't want to do that again. What am I supposed to do? They encourage me to work hard and finish early but all they do is yell at me for doing my hw. We will be in a car moving for 2 days and I won't have access to my hw I'm trying to finish it all before we go. Everyone keeps yelling at me and taking their stress out on me which makes it harder for me. I have 2 other siblings who can help but they aren't on them to help. What do I do? I'm working so hard for A's to raise my gpa. I'm trying to focus on school since I failed 2 classes last year. I'm trying to get a job. I'm trying so hard and everyone and everything is against me. I went from a 2.00 gpa to 3.00 rn the program I apply for in the fall requires a 3.5. I'm pushing myself so hard and no one else is supporting me not even my parents. They get mad when I hang out with my bf once a week... he's my only friend, he's my life and I'm moving and want to spend time with him before we are long distance. What do I do?
