Are you trying to socialize with people who are reasonable? By this I mean, people who can think and understand, and even have compassion?
I understand the frustration of all this. Many people that I am in contact with see me as very capable. If they could see the hard work behind my "social front" they'd be very surprised at how hard it is for me to seem "normal." They might wonder why I put myself through so much.
If you ask yourself what is it that you need from interactions, you may discover that you are asking the other people to give you something they cannot. You feel fake, or out of place because the person you are is out of tune with the whole of the situation.
I act "normal" to have a job. I am in a line of work that has many expectations. My needs are filled by teaching and nurturing people in their spiritual lives. So, in my case the socializing is in a context. Context IS everything and makes socializing easier for me. Some other parts of the work are very, very damaging to me and makes me exhausted. I never show my whole self to anyone, they would make fun of me just like the kids in school. People just don't understand what it's like to be this way. But, I am not discouraged anymore.
It gets better, don't do anything rash.
Just my take, your mileage may vary.
