Laying in her crib talking to herself.

She's slept 30 minutes TOTAL the entire day. How is that healthy? All she does is scream and keep herself awake. I don't fucking get it. I'm going crazy. My ears are numb from the screaming. She's fed, changed, being rocked and won't stop. She won't fall asleep or stay asleep yet she is exhausted. We went on a drive which made her fall asleep but as soon as we got home she woke up. Not to mention I have two online tests due for college and I won't be doing those lol. I just wish I knew what was wrong. I wish she would SLEEP.
