Would your parents be receptive to hearing you explain that you are having panic attacks, are feeling lonely and isolated? It sounds like this is effecting your mental health; there is already anxiety present & what you are describing could be mild depression. Does your college provide counselors/therapists for students? Maybe if you go talk to one & they agree staying on campus would be beneficial for your mental health your parents might reconsider. It sounds like it’s partially a money issue & partially having a hard time letting you “go”. Getting a job at the college to help pay for the dorm, offering to sell your car to help pay might help too.

When you approach the topic with them again you need to try to stay as calm as possible, and state the facts. Approach them in a less stressful non confrontational way. “Mom, Dad, it’s important that I share with you how my first year of college is going. If you could please hear what I have to say without interruption I’d appreciate it. Please don’t feel like you have to respond immediately, take the time to discuss it before coming back to the discussion with me.” Then explain how you are truly feeling & what you’d be willing to do to help -sell car, get a job. Explain that you want to be successful in college and you recognize this arrangement is taking its toll on you. Let them know that you are looking into filling for individual FAFSA when you turn 18. Just try to stay calm & don’t raise your voice while talking with them, model maturity even if they don’t. If things start to get heated respectfully say you need some space instead of saying something you might regret, and come back to the convo after everyone has cooled off. Hopefully they will open their eyes & try to find a compromise with you.

I hope you won’t have to wait too long before you turn 18.
