I don't want to downplay the struggles that are unique to having aspergers, but many people are miserable at your age!
I know I was. It was a combination of being extremely sensitive, recovering from childhood neglect, low self-esteem, and difficulty relating to other people.
Highly sensitive people and AS people have something in common: immunity to social conditioning. The expression is different as in I can definitely do what people expect--I can play the game--whereas someone with AS may or may not be able to. But I don't care to, but when I was your age I didn't realize that I didn't have to. I can't stand pointless chit-chat, fakeness, when people say things like, " I really want to see you" and we hardly know each other. Or, when people say, " I'll call you".... " Let's hang out"... or anything like that and they don't mean it and never follow through.
I cannot tolerate betrayal, teasing, gossip, illogical conversation, being emotional without reason, when people stay angry without resolution, defensiveness, etc... etc...
But when I was your age, I couldn't name all of that. I pointed it all at myself, I thought that I was the defective one and I just wanted to relieve my feelings of alienation by fitting in.
I hope that you never fully fit in! Fitting in means becoming immune to what's really going on, in service to what is socially acceptable.
Instead, I wish that you could develop self-esteem, find people like you (like here on WP) in real life, and learn who you are and what your needs are. If you make that your goal, surely you will get there.
If you have the resources, I'd start with some therapy. Find a professional that you trust and who fully supports you to open up to. Use Alice Miller's website to help guide you in finding a good therapist as there are tons of bad ones out there.

Then, are you taking care of your health? Eating whole foods, drinking plenty of water? Cut out all processed foods, soda, sugar and you will feel a million times better. Are you getting exercise?
That may seem unrelated, but it's actually the very base of feeling good. I know that when I eat a lot of sugar, I start to feel terrible incuding feelings of self-hate. If only I realized the power of nutrition at your age!
Hope you feel better soon! Keep reaching out!
