What's with my shyness?!

Geez I saw her again and I was caught off guard.. Was daydreaming while walking..yes daydreaming..when suddenly I saw her.. Atleast I had the guts to look at her but my body was frozen. Will I ever have the courage to come up to her and introduce myself personally? I wouldn't want her to just wonder who she chats with and never show up to her personally.. Well the thing is that I didn't get much sleep *thanks to insomnia* and I wouldn't want to show my groggy face. Hopefully next week I'll be able to gather my thoughts and talk to her..
