SomethingWitty, I really think your best option would be to focus on getting some distance from your parents. They sound toxic and extremely abusive and going back is only going to offer you more of the same. Commit to getting started and settled at Uni, find some student accommodation and perhaps you could connect with the counselling service that most Uni's offer. These are usually affordable for students. They might even be able to refer you to support groups. Get some support, it's really important if you are going to get through this. Keep reaching out here and please know you are not alone.
