No idea what to do...Lost

I have no idea how to get a guy to like me. Right now I have three chushes. One of them was in my class last year and me would always stare at me but this year we arent to gether anymore. He isnt in any of my classes. I really want him to like me and ask me out. I have some freinds but not a lot. he knows that too so maybe thats why he doesnt want to ever talk to me. when ever I se him in the hallways, he would stare at me… I need him to like me… im always thinking about him and I dont kow what to do. do you think he likes me? what in the world should I do right now? if I should talk to him, what should I say and when? should I just wait for him to say something or do something on my own? please help me! im ruined with out any guy freinds! thanks for your help!

Ps: in your responce, please dont tell me to hang out with him…if you do… please tell me how because im going to mess up hanging out and turn out to be a dork because I would be so embarassed. just please tell me how a guy wants to have a girl haning out with him… thank you so much!
