Dazed and Confused

I don't know why, but sometimes I find myself crying to sleep at night. I dont know if it's because I don't know how to express myself and my feelings, or if I'm crying for the sake of crying. Sometimes it feels great, other times it makes my eyes hurt and plugs my nose, creating a "snort" sound which sometimes makes me laugh. Talking to people always helps, but you can only talk to people for so long before they get annoyed and stop wanting to be around you. I dont want this to happen. I don't want to feel like there's a demon inside me tearing me apart from the inside out.
