I have this overwhelming feeling that there is a group of people that want to do harm to me. I told my psychiatrist that I understand it probably isn't real and I get it sounds crazy, so he kind of dismissed it as OCD thoughts (I'm also comorbid OCD). I'm not sure he understood that i can say that but it still just lingers in my mind all the time. I used to text my friends random profiles on social media late at night thinking they were after me and he called a welfare check. 

My question is, is lack of insight a requirement for paranoia?
