I'm going to pretty much agree with what other people have said -- especially in high school, it's TOUGH to not fit into an expected role. No one in that situation is really taking the time to get to know people other than their close friends, and a lot of kids at your age haven't even learned to see people as three-dimensional, full-color characters yet. Later in life you will find more people willing to just accept you as who you are.
As for the bi thing, it is sometimes tough to hear the whole "in denial" stereotype, but honestly I think that being able to appreciate twice as much awesome sexiness probably more than makes up for it.
