A night with a 17 year old "newborn"

Oh, what a night I had last night.
My seventeen year old granddaughter is visiting. She is a young lady of normal intelligence, but she is a troubled person. (Details on possible causes of this will not be provided here....at least not in this post.)
I was pretty tense last evening having spent an hour in the car with her talking loudly non-stop, and simultaneously blaring music which is not the kind grandmothers prefer. I went to bed about 10, and dozed a bit, but just couldn't get relaxed enough to go to sleep. I think I finally went to sleep about midnight.
At 12:30 she woke me up, declaring that she couldn't sleep and had to have a Benadryl to help her. I was foggy headed enough not to think much about this and gave her one.
Then I went back to bed....and tossed and turned. At 2:30, I got up and had a cup of warm milk hoping that would help. Shortly thereafter, I again went to sleep.
At 3:30, she was again in my room. This time she said that her teeth hurt from the orthodontic adjustment done on Thursday, and insisted on Tylenol. I was muttering to myself that perhaps it was really tooth pain that had kept her awake earlier, and she should have had the Tylenol at 12:30. Should I have thought of that in my groggy state?
After I gave her the Tylenol, she informed me that even though she wasn't sleeping well, she would be up at 7. I told her absolutely not. I did NOT want her out of bed before 8 AM, because I was going to sleep in myself.
Yeah, right. At 6:50, she was back in my room. I snarled at her to go back to bed and not trouble me again until 8 o'clock.
At 7:50, she came in and asked my husband to take her to the donut shop.
A bit after 8, I dragged my weary body out of the bed thinking that I haven't felt this way, since being up repeatedly with a newborn.
I sure hope tonight is better.
