Why would you go back to Uni?
Your only option is to become self sufficient. I am sensing you are perhaps overly reliant on your parents, psychologically, mentally, financially and they probably also fear this. Hence the need for their tough love and they are essentially 'ejecting' you.
Have you ever seen the wildlife programme where the tiny baby sea birds on top of a 300ft cliff have no option but to leave the nest? They literally bounce down the side of the cliff face hitting rocks before landing in the sea. Some die and some live in that process but that life survival is brutal.
You are in danger of failing to make your own decisions and seeing others as the cause of the lack of success in your own life?
Plan your own life going forward and stop waiting for others to make your decisions for you? If it goes wrong you have to be the one to take responsibility. Explore all accommodation options, house sharing, bedsit, lodger, etc You can pass your driving test if you put your mind to it and work to pay for it. You will need a job too to pay for the rent, rates, food, going out. Sit down and look at all of the jobs, apprentices available Nationally. Decide what career you see yourself doing to earn money longer term? Make a list of your strengths, weaknesses in all aspects of your life. Work out immediate needs, immediate funds, short term, long term. Go back to college and boost your Maths, English if you need to. Consider joining the army, navy, RAF, at least you will get accommodation while earning something.
I hear you talk a lot of negatives in your post about your life going forward. I read your comments about your parents house move but they are quite entitled to do what they want to do. I am sure they will advise you or give you practical support. It seems like now is the time for you to become independent and to make your own way in the world too.
You might need advice from various charitable helplines to understand your options but this is something you can also do. Embrace the challenge. You can revisit the gaps in your education and make up any base grades by resitting courses and exams. Only you will know if you are suited to the demands and discipline needed to study at Uni, accompanied by the horrendous student debt going forwards.
