Hey Len nice to hear from you! Sorry to hear about the issues you are having. I too have social, gad anxiety type issues and things I've noticed that I do similar to you are covering the Webcam, I always make sure the doors are locked and I also look out the peep hole. One of my biggest paranoia issues are when I'm pulling into my complex I think I always notice the same people driving around following me especially if they are wearing sunglasses lol.

I don't think mine is overly a problem where it puts me or others at risk. I kind of just laugh it off after. When you say that you are hiding knives to feel safe it makes me think of past trauma. Whatever the reason I hope you can figure it out Len, sorry if I was no help.
