I was a math tutor for a while in college and I ran into a few kids, mostly freshmen, who felt like the world was going to end if they didn't get an A. These were sometimes kids who got an A in every math class they ever took in H.S. and now they were barely passing general stats. The problem was they defined themselves as the smart kid who always got an A and that was what made them special. When you add to this all of the other pressures in being college freshmen, not even counting being an athlete at an Ivy, it can be a lot to handle.
I dealt with some of the pressures of being a freshman student/athlete, trying to please everyone. Unfortunately, I went the opposite direction and starting partying at lot and got myself in a little trouble. I got my act together the following year, but looking back, I needed that release. I say all of this not knowing the details of this young person's life...perhaps she was dealing with more than we know. The last thing I said to my kids when they left for college was don't forget to study and have fun and when I spoke to them on the phone I would always ask are they enjoying school.
No matter how her grades or her running was going, she had so much going for her and everything was going to be ok. I really wished she could have confided in someone, who could have simply told her that everything was going to be ok.
