Sound like you have something else going on besides AS. It doesn't sound like any normal paranoia people have.
The kind of paranoia I may get is that I scared someone off online and said something wrong, or when I hear bad things about a person, I then end up not wanting to ever want anything to do with them because they could do the same to me as they do to other people. I tend to think the worst that could happen because I am afraid of surprises so I try to have things be predictable so if I am prepared for it, I will be able to handle it better. I also refuse to keep my hopes up for things because of the what ifs. I have been told this is all anxiety. I wonder if OCD has anything to do with this because of the paranoia and the what ifs a people with OCD will tend to worry and keep on thinking about it being unable to not ever think about it. Autism may have something to do with it too because of change and surprises I am afraid of and lot of us hate those so if we keep ourselves prepared for them and think of things that can happen, we will be expecting them when they do happen and handle them better. Plus the worrier trait runs in my mom's side of the family so she thinks I may have inherited that. They always think of the worst that could happen but they don't obsess about it like I do. My mom used to do it too and my dad taught her that worrying is a waste o time of energy because why worry about something if there is nothing you can do about it. I know I could worry about my son ending up being badly autistic because I have heard of regressive autism and how children are fine and developing normally until they reach two and half years of age and start losing their normal skills like eye contact and quit responding to their name or stop paying attention to people, start spinning wheels on cars instead of playing with them, etc but I am not worried about that. In fact I have seen NT parents online out there worrying about it so they go online and ask if their kid is autistic and they list traits that are actually normal or they are freaking out over one thing they are doing such as hand flapping or that their kid doesn't always look at them or respond to their name. A baby will get over focused in their activity they would not want to really want to respond or come to you but just as long as they still look at you and come to you when you call them, why worry? And I am the one with anxiety and OCD? What about those mothers out there worrying about their kids having autism when they are probably fine? You have to have more than hand flapping to have autism or more than one or two things to have autism. Same as if a kid has a speech delay or is slow at developing it and that is all they have, not autism.
But my paranoia is nothing like yours.
