I made a fool out of myself in front of my crush.?

I was at summer school and I saw this one girl who I really liked and she was walking down the hallway. As she was walking by, I was trying to act and look cool to impress her. As she was walking past me, I was looking at her and I didn't see the "Caution: Slippery Floor" sign and I fell right down onto the wet floor. Everybody started laughing and she even laughed. Now, she thinks of me as this clumsy freak. I feel so embarassed.
