Emily, sweetie, you would be good in a whole raft of jobs, it's only conditioning and practice from home that is making you feel that you aren't 'good at anything'. Having lived through the same, I can reassure you that you will be great at some thing, and you will feel the satisfaction of doing it your way.
Some parents want to help and guide their children into areas that they feel are safe and secure, and blinker themselves (or deny), other options, and often forget that as a young adult, you are entitled to make decisions about your own life.
As the debt is in your name, it's up to you.
If you can get a job, and you think you can make the numbers work (food, bills, transport, insurance) in your local town, if your dad did decide to ask you to leave, then all you would need to do would be work out when. I'm sure your mum would have a lot to say about that however!
The hardest part I find is making the choice and sticking to it. Life is always full of options

and I'm sure you can make a success of it!
