All it has gotten me as been betrayed and people who say they care for me but really use me at the end.
I want to become less talkative to the point where I use to be that I don't talk to people and just nod my head. I want to remain quiet. I am tired of trying to make friends when they really are not friends. I only find neurodiverse people are actually friends that I can relate too.
Seriously the best advice I can give you is to put a complete halt to how easy it appears for you to so quickly open up to much of anyone and tell them of all your troubles.
Humans- not defined by NT or ND considerations can be predatory and transactional. It's just who and what we are as a species. Meaning that if you're so prone to sticking your neck out to others even with honesty and sincerity, there's a likelihood that people will quickly grow tired of hearing your woes and abandon you. Leaving you to lament your life, and yet repeat this cycle of behavior, tragically thinking there's always someone out there who wants to hear your plight and problems.
In essence, it's not that you need to cut yourself off from people as it is to change how you interact with them. With consideration to two things which you may find very difficult to achieve:
1) Be genuinely friendly. To be positive and upbeat on a consistent basis.
2) Not to "infoshare" your problems. To learn to give- and not simply take from people, without a sense of urgency and appearing "needy".
People may be willing to listen to you, but that they will turn your back on you when they determine this is all you have to offer. A response I might add that isn't exclusive to just NTs.
And consider your first inclination was to visit this site to get the consensus of others. If you want to be isolated from people, you have to act accordingly. To make decisions unilaterally, without any consensus of others. In my own opinion, I have observed people on the spectrum who could be defined in one of two ways:
Those who crave solitude and practice social isolation, versus those who cannot. In essence not all of us are truly introverts. Some are extroverts and always seeking the companionship of others. You strike me as being the latter, while autistic persons like myself reflect the former. Differences that (IMO) are the inherently a result of who we are from birth. In other words, you can't simply learn to be introverted if it's not your natural state of being. -Autistic or not.
Leaving items 1 & 2 listed above as your most likely alternatives. Things you are probably more able to learn compared to leading a life of isolation, which I suspect is simply not in your nature. And yes, I can think of two other members of this community I would probably say the same to. That you are not alone in this respect.
You don't want to be "antisocial". It simply isn't who you really are.
