<human>: Can you summarize the given text in a few sentences?

I've had my eye on this girl in my class for months now. She's the prettiest person I've ever seen. Last week I finally built up the courage to start talking to her. We talked in class for about 30 minutes, really flowed well and then the bell rang. I was too wrapped up to ask for her number or anything.

The problem is, that was the last class I'll ever have with her as we are graduating tomorrow. Today was the last day of classes, and I looked all over for her to talk to her again. And I did see her. But I froze. I saw her waiting to enter the hallway, it was the perfect opportunity for me to start a conversation. But I was so scared that I walked away. Realizing my mistake about 10 seconds later, I quickly turned back and made my way back to where I saw her. But she was gone. I suspect that she had a class in the hall so I waiting in my car until the final bell was about to ring, right outside the hall doors to hopefully see her again. I didn't.

Tomorrow is the last possible chance that I have. I don't want her to slip away, I'd be suffering over the summer knowing that I had a chance and blew it. I hyped myself up and thought that I had the strength to say "hey" or something, but I don't. I have little confidence when pressured into a situation like that.

Tomorrow will be graduation practice and she'll be there with all the other seniors. However this time, she'll most likely be surrounded by her friends. There is no way in hell that I have the confidence to talk with her, or even ask her to add me on facebook in front of people she knows. I believe that I can, but I know that I'll fail.

Any suggestions?
