Although she's being rather upbeat and cheerful about the career day - and about seeing her parents in particular - it might have been noticeable during the sessions that she was looking more frazzled than usual, particularly when looking over the various Quidditch booths. Depending on who your character is and how well they know her, they might put this down to homesickness, worry about the future or the Team Fabulous Great Cupcake Debacle (tm!) or even a mixture of the three.

However, the clues about what is really bothering her lie in what she's up to when she is out of class and goes to hang out by herself. She's been going for long runs and (not so) secret flying sessions - not for 'me time', but to test how well her old injury is holding up. She hasn't mentioned it yet, because she's worried about what people will think, but this is the time by which the Healers said she should be able to get back on a broom and fly again. In essence, she's physically pushing herself to see what she's capable of and if she'll ever be to the standards she was at before she got hurt - and THAT'S what's upsetting her.

Career Day basically reminded her that she has options, but she's flailing about whether she'll ever be any good at them. Being in 7th year is blowing her mind, so she's throwing everything into her managerial efforts to take her mind off things. The TFGCD is upsetting her perhaps more than it normally would because now she's doubting herself on the managerial front as well as the playing one :(

In any case, if you have a character that knows her, do as you see fit. Plot? :)
