I used to, and still do, get paranoid a lot about a lot of things. Sometimes I think that people can see me through the TV. I also believed that aliens were after me and they were trying to communicate with me somehow. When I walk around I feel like everyone is watching and talking about me and there are cars that seem like they follow me and do surveillance on me, I hate the feelings and I know that they are irrational but still I have a bad feeling in the back of my mind that its true and the feeling wont go away. I havent been diagnosed with anything yet except Depression but Im pretty sure I have some type of psychosis because those feelings are not normal. Just a lot of weird thoughts like you had, I dont take any medication though.
