Hey young lady/man,
Take it easy - altho 2 years will probably fly past, it is still some time away! You might meet other people your age during these 2 years or soon after - maybe join some clubs e.g. sports one if you are into sport or other social places where young people gather - you will robably meet people that you get on well with.
Even after the 2 yrs are over, if you either go to university or start a job, you will meet many people with varying personalities, hobbies, interests, pastimes - I would strongly suggest that you cross that bridge when you come to it - no use worrying about it r n, yeah? Make the most of today and I can assure you t-rrow will be even -better!
A famous person once said that life is like a train journey - people get on & off at various stations, some u get to know others just fleet by.
Relax, with medicine progressing at the blistering pace that it is, you have 100+ years ahead of you! Relax you will be fine!
Listen to the songs:
"Happy" by Phil Pherell
and:
Work hard Play hard.
Go on grab your problems by the neck - you can do it!
