Hey sweetie, plan to protect yourself. If the family is having a pre-grad dinner then make plans to be there or not. Have youyr own wheels so you can leave when you need to and have a safe place to go. Parents? Sister? So you can be there for the grad and for pictures and disappear while the rest happens. Protect yourself. I know I really need my time alone. You will do fine. The hospital thing doesn't sound quite so cool you know? I have even resorted to motel rooms I can't afford when I need space. Thankfully I have friends who let me crash when the world gets too intense. Good luck. By the way, my youngest graduates this year also.
