Wednesday went to my doctor and told him everything but i just got sent back home to try to sleep Thursday it seems i slept for a few hours but get up tired. now this Friday at 1 am i fell asleep my mom said cause she turned off my tv but i woke up at 4 am saying i been awake all night what to do

Sounds irritating and simple, but try exercising more in the day, less caffeine especially towards the end of the day. Try not to do stimulating things at night like computers, tv or phone. Read a book, write or draw, something classical.
The important thing is that you get SOME sleep, and gradually build it up, even if it means forcing yourself to stay awake in the day time and lying painstakingly for hours in bed trying to sleep.

Lack of sleep can be really bad, and in severe cases can lead to psychosis. Sleep is essential to a healthy functioning system.

Hope this helps
