i have tried to meet new people but i always felt years younger than i am...like mature wise. I always liked adults better when i was in high school as friends.
You could be writing about my experiences - I felt the same. I always got on much better with adults than my peers. I recently made new friends at TAFE with two other students with disabilities - one asked me if I had acceptance issues at school - I went "Hell Yeah!"
Meeting new people is usually easier when you are doing, learning or finding out things (*please insert something that is relevant to you* joining forums on birds, star trek, ptsd, science, building computers, birds etc etc and learning things like building models, learning to identify birds, learning to dance, hanging out with the stamp collectors, doing bush care, learning a new craft or hobby, bush walking, disco dancing, belly dancing, building starship enterprises, practicing your Klingon, painting, drawing, beginner's classes are always good because you are not alone in not knowing anything.)Sometimes there are get togethers for those of us who are have trouble connecting with other people. I used to run a few and I got a lot of feedback that they were not only helpful but people made long term friends. I know this might seem lame but I joined up at disabilities at one of the places I study and I have made a few new friends - and there is no need to explain anything.
Remember that there are a hell of a lot of people out there that feel the same as us. So one strategy can be to go and talk to someone standing on their own - even about the weather is okay. It is all about connection, not so much about content.
