I'm 16 and on Sunday nights i can never get to sleep till around 4am, and when i wake up for college at about 7am i am always extremely tired throughout the day but i always..

feel irritable
have itchy skin
muscle aches
need to urinate more (only slightly, i often feel like i need the toilet but when i go i often don't)
