No.
You can’t actually ‘start over’. You have a college record, and you will carry it with you, through college and into grad school admissions.
@parentologist is right: you need to talk to your advisor or Dean and withdraw now, ideally so that you have no record at all for this semester. Hit the ‘pause’ button, because it sounds as if you are too overwhelmed right now for serious decision making.
So, tell the college that you need to get your life in order and need a leave of absence to do it. Those are ‘true facts’, whether you ultimately decide to go back to York, take some classes at a CC (which you can do while you are on a leave btw), or transfer to a different college.
Be honest, but remember that you do not have to discuss all of the many possible outcomes you have mentioned with them. When you have sorted yourself out, then you back and tell them what your plan is.
