Dude!
If you walked past her and she was crying... you should take the opportunity and ask her if she's alright... instant ice breaker!
she'll get the idea that you care for her in no time, and I'm sure she'd love some comforting...
But I have to tell you something... Don't blow this problem out of proportion (for yourself). It's just a girl, a human being like yourself, talking to her shouldn't be a problem at all.
"Hi, I've been meaning to talk with you for a while now, but haven't got the courage of doing so... but now I'm overcoming my fears.... Hi! How are you doing?"
How would You react if she said that to you one afternoon? Even if you didn't have a crush on her, you'd be happy right? Someone who was a bit scared to talk to you? Kind of hard not to add 1 + 1...
I am pretty sure you wouldn't think (or say): "Hah, fuck you dipshit... LOLOLOLOL twat... idiot! LOL look at her lol hate her!! hahaha" right?
-insert psychological mirror here-
How would She react if YOU told her that? Even if she didn't have a crush on you, she'd be happy right? Someone who was a bit scared to talk to her? Kind of hard not to add 1+1...
Now, why ould she say (or think) "hah fuck you...."? She wouldn't! (unless she's a damn idiot!)
get what i'm aiming for here? I hope you do.
I found my girl in school, tracked her down and added her on a facebook-ish site... talked for a while... waved at each other in school, and finally one day i went to her and poked her, saying hi with a super blush. She turned around, looked at me. and turned away. then turned to me again, opened her mouth. and turned away again. and then turned to me once again, blushing like mad, saying hi. saw each other in school, and talked a bit, went out to drink hot chocolate in the winter afternoons, talking a bit about anything (Finding out she's a gaming manga anime nerd, whoop), and just talk about each other for a while.
Eventually, I kinda worked up my courage and said: I like you a lot.
then we hugged.
then we sat down.
and kissed.
and kissed some more.
we were together.
now that's 3 years and 1 month ago.
