I Am Confused

I got my AS results today, and although did really well overall and I passed the subjects I need to get into next year, I hate the sixth form/college (I live in england) I am at and I don't know what to do next. The two friends I have at college are both leaving and spending next year somewhere new. So I can either stay here, unhappy but knowing it's likely I'll pass, or I can go to a college where I know I have friends but I'm not familiar with the teaching - and I'd also have to go to the effort of organising enrolment there too. I don't know what to do, whether to stay or go. I hate it where I am but I'm terrified of changing it in case I fail.
