HOW TO GET OVER A CRUSH? PLEASE HELP ME. IM IN A LOT OF PAIN.CAN SOMEONE PLEASE HELP ME?

Ahh, I don't think you were bothering her, she's just shy. The fact that she rushed away might mean that she's beginning to like you back. Keep your esteem high, and keep talking to her, hence the confused face when you thought you were bothering her, she'll be glad to see you. :D
