(((((((((((Alistair))))))))))))
Welcome to PC
I kinda know how you feel, I used to be in that situation and for other reasons I now can only put one person to who I am friends with (and he's 300 miles away). It's difficult feeling as though you don't fit in and unfortunately I can't tell you something that will 'fix' your problem straight away.
The red head thing, that's very stereotypical and there are lots of people who don't let stereotypes sway their judgement. Problem is finding them.
I love the name Alistair (I'm from the UK), it's a fairly common name where I come from and it's seen as a manly name. It's often shortened to Al here too, have you ever thought of introducing yourself with a nickname?
Have you thought about joining a group? Has your college got a karting group or formula student team?

I wish I could give you some more advice, I know how lonely and depressing it gets.
If you ever need to talk or just rant about something the people her on PC are really nice and there'll always be someone who'll offer their support.
Hang in there mate
