Hi, my name is Danielle, and I'm 15... My teacher and my friends have been worried about me lately, and today my teacher came up straight forward to me and told me what they've noticed... she said that lately ive been talking fast, and i know i havent been able to concentrate, and my mind just races sometimes and i cant think straight; and she said that sometimes i get very angry without reason; and she said ive been sometimes really hyper; ive been irritable; my moods have been changing every few hours, one hour im too happy and the next im upset; ive had difficulty paying attention and concentrating; sometimes i dont even want to do anything but just sit in school; i havent been very social at times(more than usual); sometimes im just completely drained of energy and i dont even want to move; ive been having trouble at school, and ive been getting angry alot lately for no good reason at all... im not sure if this is a problem that could be fixed, or whats wrong, or what.... what should i do??
