Eeek, I feel exactly the same way.
My Form Teacher (homeroom teacher, I think in 'American terms' not sure though

) is always telling me I need to pick a career now, find out what I want to do now, and that I should know what I want to do with my life. The careers people are always asking me what I enjoy doing or what I'm good at. I can't answer them, I'm not particularly good at anything. I'm an all-rounder, but its easier to say what I am not good at. Most people have 'a thing', an academic subject they are amazingly good at, I just don't. I'm in 'top set' for everything (does that make sense for my American readers? =S) but I'm in the middle of all of them. So I don't stand out.
It really sucks because I have certain people who work at my school telling me that I have "potential" but I basically wont succeed because I don't know what to do :l
Friendswise, has always been rather strange. I have a couple of people I know I will be in touch with for ages, but I've never had a
best friend in the sense that some people do.
On the otherhand, a lot of people feel the same way you do, I know I am one of them in a way

Atm, everyone seems to be moving on with their lives in various ways, and I appear to be lagging behind, waiting to discover something that will move me along.
ooers, that was long.
