When I was your age, my life felt hollow and pointless. I yearned for the friendships and romances I saw other people having and felt alone and incomplete. I didn't realize it at the time, but what i was really fixated on wasn't friendship or romance, but the desire to simply be like everyone else, and have what they had. Once I was able to accept and love myself as I was, I realized I'd been looking to others for some kind of validation and never got it, so I felt miserable all the time. Plus I think the young raging hormones thing made it all worse too.
Teen years are tough on everyone, but perhaps even more so with us sensitive aspies. Learn to love yourself, don't feel like you have to be like everyone else, and spend more time working on the future you. Once you're a little older, and have these awkward years behind you, it'll be easier to properly gauge your societal limitations and whether you are destined for a relationship or not.
I'm not saying don't try now. I'm just saying don't make it the most important thing in your life, so it can't compromise the rest of you when it doesn't work out.
