As others have already suggested, you should definitely contact the financial aid office. Additionally, you should contact the following:
-People in the EECS department. Maybe people in EECS have jobs you could do, know scholarships you can apply for, etc.
-Contact the College of Engineering. Maybe they can suggest scholarships for you and/or even award you some.
-THE COMPANY YOU ARE CURRENTLY INTERNING WITH. If the company that you are interning with really likes you and they want to bring you back, then they will probably try to help you. Ask if you can work there during the school year and receive a tuition reimbursement or something. There are employers that will pay/reimburse an employee’s education (maybe not all of it, but some is certainly better than none).
You may want to be careful about how many details and how personal you get when you explain your situation. You want them to understand the you don’t have enough money part. Diving too much into why your relationship with your family is the way it is may make some people (including you) feel uncomfortable.
Good luck! I hope you find a way to continue your education at the University of Michigan!
