Paranoid thinking

I don't know what's wrong with me, but sometimes when I'm alone, I get very paranoid...as if I'm afraid of being alone. Like I'd feel more comfortable if someone was just there. So when no one is texting me, or I'm alone in my room on a bright Saturday but the campus is dead (and again no one is texting me), I actually start to feel this sense of worry/fear/anxiety.

Probably because I'm afraid of being alone with just my thoughts sometimes...
