Well you're going to high school I just finished it and now I'm going to university :D
I felt the same way..but there's like so many people that think like that and you'll all be shy first day but in a week or so you'll get close to everybody dw. Alot of people will not known anybody and just be best friends with them.
I joined High School (Over here we call it Secondary School). It felt very nerve-racking, and also quite exciting at the time.
I started off as a little minor, sitting in the corner of every classroom, wishing I was back in the nice warmth and friendliness of my Primary School, where every teacher knew your name.
But I wouldn't worry, as I soon made friends using a variety of different techniques. When I was in Form (Where you go there twice a day to be marked in as in school), I made friends first with the people in my form, as for the first two weeks, we went to lessons in out forms (Although I don't know why). So, gradually, as you get put into Teaching Groups in Year 7, and sets in Years 8+, you will make a variety of new friends as every year you can be garunteed there is someone different in your new "Set.".
I hope that that helped in a lot of ways.
