<human>: Can you condense the text into three sentences or less?

Hey Reddit.. So i recently hooked up with this 17 year old girl that i really like (I am a 17 year old boy), I've known her for so long. (We are in high school)
We've only been dating for about a month now, and she has developed a sleeping disorder for quite some time now. She "wakes" up 5-6 times a night and walks around, and then realizes she is up. She only gets around 2 good hours a night of sleep. 
This sleeping disorder has messed her up. She cant think straight, being obviously exhausted and sleep deprived. 
I've looked up many treatments to sleeping better and it just isn't working. 
She is feeling overwhelmed with everything including being in a relationship with me, and we've tried talking about it. But we don't get very deep in the conversation because she doesn't even know herself of what she thinks about it. She really likes me and cares about me so much. She just isn't used to dating and she feels like she is in a trance. She freaks out and thinks she's pushing me away because I feel like I'm blaming myself. 
It doesn't seem like a big deal, and then it does. I just don't know what I can do to help her. 
So this is where you guys come in. I need all the advice i can get.. From sleeping better, to helping my relationship with my girlfriend. 
She doesn't have any real problems, and she's a straight A student, a good girl, doesn't drink or smoke or anything.
