I'm sure it'll work itself out. Hopefully your parents or your caregiver is working to sort it out.
Change can be scary and when I was your age I went through a lot of change and was scared out of my wits at the time. Leaving home to start university was very tough for me but it turned out to be the best thing going. I fit in more and made a few friends - I look back on that time as some of the best years of my life.
The place you're going to looks beautiful in the pictures and you'll be there with people like yourself. Hopefully you'll be able to make some friends there and enjoy a bit more independance.
I wish you the very best in your new home - let us all know how things are once your settled in there.
Take care
