GAD vs Paranoia?

I thought this was just the Anxiety, but I'm starting to wonder. I've had paranoid thoughts since childhood. I thought that people from school were watching me through my windows at night, that my eyes were video cameras, and that certain people could read my thoughts.

As a teen, after sex ed, I was terrified of getting pregnant and thought things like using a bath after a man could cause it. I also used to think that people would break into our house and rape me in my sleep or even that "ghosts" would do it. I know this sounds ridiculous but those were just my thoughts. I'm in my mid 20s and still afraid to have sex, due to the fact that no birth control is 100% safe.

Now that I'm older I find myself sometimes paranoid for example that someone is going to kill me even in my own home, to the point that sometimes I will feel a need to turn the lights off when I'm having dinner because the dining room may be seen from the street and I feel like someone is going to shoot me through the window.

I also feel extremely uncomfortable with talking to myself even when I'm completely alone at home. I have no idea how people do it, it feels very awkward to me.

Is this normal for GAD or is it more like paranoia? The weird thing is that I personally wouldn't mind dying, but I actually find it almost like "embarrassing" if I were to die, because I know a lot of people would be affected by it.

I see you've posted in OCD. Have you any formal anxiety related Dxs?

I've always been paranoid, sometimes to a greater extent than others. My block to having been nite sexually active as I have been, was always fear of STDs. I've had other similar fears, being watched, talked about, etc.

Have you taken any self tests to see if there's any direction you ought to take your inquiries into?
