I absolutely despise being a teenager?

You sound like a very intelligent and evolved young lady. I hated my teenage years, too. I hate nothing more than when adults say those are the best years of your life, because that's just not true! I am 20 now, and yes, teenage life is more sheltered...adult life has more challenges, but being able to handle things yourself is just more satisfying. Even if you fail, it helps you grow! It's alright if your friends are older. I guess my only suggestion is, you should research emancipation. Any individual that is sixteen or older has the freedom to emancipate themselves, which means you are completely independent. But be very careful, because there are things to think about..I doubt your parents will like this idea, and if you are able to emancipate yourself, I think your parents need to consent. They will not be forced to pay for healthcare and other very important things. I don't know much else so, as I said, do detailed research. I would also try sitting and talking to your parents about these feelings, if you haven't yet. I think that if you came to them stating that you feel trapped and isolated, they might understand. No doubt they are older than me, so they will have even more experience and advice! Best of luck!
