Over the past couple weeks I've had a very big problem with sleeping. I am unable to fall asleep until at least 6am every morning and I've been sleeping until about 11am to 1pm everyday.
After I wake up, even if I've only gotten a small amount of sleep, I feel wide awake until 6am. I don't understand why I can't sleep anymore.

Plus, school starts in a couple weeks and I can't keep this pattern going.
Any help with this or ideas of how to get better sleep would be appreciated.
