It's sad to be torn apart like that. None of us know your precise options or the ins and outs of your familial relationships. You said the only reason you were going to stay at dad's was the closeness to your job and he had a spare car. So, if you can find other living arrangements, where you can have access to a car, I would seek them out. Please let us know how things work out. I feel so sorry for you to be in that situation.
