So you want to move out, assuming you're in a city look for a room in a share flat. It's cheap and it gives you a reference once you look to rent your own place. Then for a job, get that asap and get anything. Literally anything that is full time (40 hours per week). Beggars can't be choosers and you have to understand life is going to be absolutely dogshit terrible for months. You should be working as much as you can, and saving up.
Immedietly start looking for a better job. There is no loyalty in the workforce. If you get a better wage the next day, take it. Just dont show it on your resume. Cut out the jobs you stay in for a week, and buff out for longer the ones that look better on a resume. Essentially you should be looking for some kind of apprenticeship. Don't expect to be able to finish uni.
Now with that put out of the way, save up enough to live in a hostel for a few weeks (in the US I'd suggest $400, that should get you accomodation and "enough" food to survive) then immedietly tell your Dad your decision. If he kicks you out, you have a plan. If he doesn't, then thank God for your luck.
Ill pray for you OP. I hope everything goes well.
