I'm frustrated that my crushes are getting out of hand
What makes you feel that they are getting out of hand?
I feel like I can't control myself when I am around with them.
I understand what you mean. Maybe you should seek help for controlling your crushes. Otherwise, your crushes will get very annoyed with you.
But I want them to notice me.
Getting notice for being positive, not by being controlling. You aren't even in a relationship and you already seek control.
