over thinking

everything people say to me I overthink, your words will sit with me for weeks, your insults cut deep, even the joke ones, they lay on the top of my mind, as I think more about it, I can't help but agree with your words, every bad thing you say I overthink about, the words constantly wrapping my mind, as I can't stop, I can't stop but to think that your right, what if you are right? I'm annoying, ugly, selfish, overdramatic, fat, useless, a disappointment.... your words run across my mind like in a marathon, running faster then I can think about them, bringing me down once I get back up, but I always let them get to me, I overthink on everything as that's how I know, truth or lie? I guess I will never know
