I feel like paranoia has overturned my life. I keep thinking that someone will break into my apartment. No matter how much I secure my door or how many times I check to make sure I've locked, it doesn't go away. I don't know anyone malicious, but I keep thinking someone will show up and try to break into my apartment. Because of this, I always drag my laptop around, everywhere I go. My Dad got a little angry with me, cause I kept dragging it around, and I kept double-checking the door whenever he would lock it and asking him if he's completely sure he locked the door. 

Last week, the police rang on my bell but then left soon after I buzzed them in. I don't know if they made a mistake and I haven't done anything illegal, but I couldn't put it out of mind. I kept checking my mailbox, looking out my window, then there's this van that's been parked outside for several nights, it's freaking me out. 

Does anyone have similar experiences? How do you cope with this?
