I'm going to be honest here, so forgive me if it comes off a bit harsh.
#1: You are not suppose to be doing anything. There's no guidebook or rules. You may be really out of shape or be awkward or have poor hygene. If you keep waiting around waiting for things that are "suppose" to happen they are never going to happen. You have to make changes to YOURSELF, small, slow and steady.
#2: Are you talking to girls in your league? If you keep asking the prom queen out and you are a normal dude, I'm sorry but you are always going to get rejected.
#3: Have you tried just letting your natural attraction out and stop trying to force it? At first I made the mistake of hitting on all these hot women and I got rejected. It wasn't until I accepted who I was and what I could get that I started hooking up with a few fat chicks and not so attractive chicks. But those times were all great lessons and gave me the confidence to date hotter women and I eventually landed a relationship with a gorgeous women. But I would never have dated her if I didn't make out with a whale in the back of a tavern and finger blast her like I was digging for oil. Practice makes perfect, even embarrassing practice.
#4: Getting a girl should be the last thing on your mind. Get into decent shape first, commit to one good hobby, find a gym friend or at least one person to hang out with, start going to things on your own, settle into a decent social life and THEN get a girl. Everyone wants to do that in the OPPOSITE order. That's the trap you need to avoid and have fallen into.
