I'm not too sure if this is the right place to ask, but it's the only seemingly relevant forum to bring the questions up on. I was diagnosed with Asperger's quite some time ago which came with some anxiety problems. However, after thinking about my behavior in the past, I'm not too sure if that's all there is to it.
I have been having these feelings of being watched, especially in front of windows, no matter what time of day it is. Any opening leading to another room or outside makes me incredibly nervous, sometimes to the point of keeping me up at night. I pace back and forth when I get near them because I feel that somebody will attack me. I have been losing sleep lately because of it, and I typically can't feel safe until I move away from them. This compounds with the overwhelming feeling that I am going to die soon. I've also been getting this feeling that my friends, family, and everyone around me secretly hate me and only keep me around because they feel they have to. I know these things sound silly or unrealistic, but I can't help but think I'm right about all of it. Are these things somewhat normal for anxiety sufferers, or does it sound like the beginning of something else? And if it is unusual, what should I ask about when I get this checked out?
