I wasn't aware that you were depressed, but I generally don't read people's blogs on JV. This situation sounds a little too complex for my commentary to have any tangibility, so all I can really do is hope things go well for you.
Do you think that when you start at university some of these problems will abate? It becomes easier to be yourself when you're parachuted into a new environment, especially when you realise that those predatory concerns you may have had, about whether people would mock you for not being heterosexual for instance, turn out to be greeted with absolute apathy- nobody cares, because everyone else is living in their own introspective world, worrying about whether people will judge them for their trivial differences.
