Ditto here. I haven't had friends since high school and I'm 34. When I was your age I wanted friendship badly, but after years of repeated rejection for being "too different" I stopped caring about it. It was a rough 2-3 years coming to terms, very suicidal, very depressed, just not good. That being said, I'm very glad I did it and survived it, I know I don't actually need people to survive and enjoy life now. I'm male though, society doesn't expect us to be pillars of socialization like they do females, my path was very difficult, with society's expectations yours may be even harder.
I always found it ironic that I'm well versed in dozens of subjects (my special interests) and yet can't hold a conversation with an NT for more than 5 minutes.
Example--
Me: Paleontologists discovered a new dinosaur called Dreadnoughtus that's the largest dinosaur ever unearthed. It will change the way we think about weight mechanics in animal life.
Other person: That's great. How about that weather, it sure is cold isn't it?
Me: um yeah it's cold, we all have thermosensory receptors, we all feel cold, was there an underlying point to that statement?
Other person: just making small talk, don't be so uptight. Did you see the new Avenger's movie, it was awesome?
Me: ...yes, I was socially obligated to see it, and I thought there was no character development to draw me in, but it wasn't bad.
Other person: No it was great, they had all kinds of cool explosions and special fx. You're stupid.
So, when I came to realize that conversation was about as deep it was going to get with my sister species I realized it really wasn't worth my time. Since then life has been a lot less stressful. I grew up with the concept that everyone could think, and think deeply, and that the people that didn't understand just hadn't grown up enough yet to use their brain power to it's fullest extent. I realize now that humans are just dumb animals, and it's best to treat them as such.
They will respond just like dogs will. If the human is panting and begging, constantly by your side that means it wants a treat-- so if the human is female you find something about her appearance and compliment it, and it's male you mention how strong he is. When you first meet another human you need to sniff their butt to tell if they're the "same" as you, so you talk about the weather, and fake interest in the latest sh***y movie. This will show that you can be one of their "pack". It's really very inane and a waste of time imo, but the vast majority of humans still need those animal cues to operate. Add in that society trains people to respond to instinct, not thought, and it's easy to see why humanity has such dire problems...ugh, so glad I live out in the boonies and completely insulated from it all, mostly.
