I had to constantly make new friends growing up (my Dad moved us around alot with his job) so I know where you are coming from. As far as highschool goes, I never saw it as the golden years, more like a bunch of people trying to impress each other that will usually never speak to each other after graduation(minus the friends request on Facebook, lol). Don't fall for the hype that television shows try to sell you. The best advice I can give you is be yourself no matter what. The more you try to be peoples friends the more they won't want to be...I know sounds stupid but its the truth.
I had a group of "aquaintances" that thought they were too cool, too good for me to hang out with them. So I just quit worrying about it and did my own thing. Funny thing was once I quit trying to hang out the more they wanted to. Find yourself, be yourself and be ok on your own. From your posts you sound like you got a good head on your shoulders, don't let others ruin it. Focus on your school work, highschool will be over before you know it. Good luck and I hope this helps.
