I think I need help Closed

When Dove entered the library, she was very confident about her homework. She knew there will be a lot of books to help her. Actually, that was the reason she went here to study. Moreover, it was in the morning, she took a great breakfast, took the time to digest a bit so now, she had the perfect amount if energy to start (and she hoped finish) her homework.
While walking to a table, a little hiden by the bookshelves so perfect to work peacefully, she noticed only a few people were in the room. This plus her inconspicuous table were the perfect match to be on her own and focus only on what she had to do.
Now that she was installed, she read her textbook and realised she must search a book to help her. She stood up and searched in the shelved a book that takled about the gargoyles history and, she hoped she could find both, about the gargoyle strike.
She didn't have to wait that long to find her happiness, a book about gargoyles that includes the two things she wanted. Perfect. Now, she just had to read it and to answer the questions of her homework.
That may have been between almost an hour she has been reading the book and try to understand the first question, and she still haven't answered to it. "Ho no, she will take longer than I thought..." she whispered to herself. She couldn't understand what was happening to her, usually, she would understand quicly, make some research to complete her homework and leave the library or her common room after one or two hours. But two hours was the maximum, she almost have never done a work for that long and... "Wow wow wow!" She almost shouted. All the eyes (even if there were not so many) looked at her before going back to their business. But if Dove said that, it was because she realised she almost fell asleep. How was that possible ? Two hours ago she was energetic like never. She had to focus more because she didn't want to leave the library before finishing her homework. However, whenever she wanted to read another time the first question, the onky thing she saw was blurry text. After all, laybe she needed a little rest, so she closed her eyes for two minutes, so she could be more awake to continue. Two minutes ? Actually, she was asleep on the table for almost an hour, and still didn't wake up.
