I can't tell is what I'm experiencing and losing sleep over is paranoia or an "irrational" fear (I use quotes because I don't think it's entirely irrational). I don't sleep much at night because I think someone is going to come into my house and murder me. I check my doors several times before I go to bed. I feel like they watch me and I'm suspicious of everyone who even relatively lingers near my house. Everything I hear at night makes me think it's happening so I'm constantly vigilant. So I'm not sure what that would be considered. Any thoughts?
