What exactly do i need to do?
My biggest physical flaw is that i look 16 when im actually 18, does that prevent this from working?

Just broke up with a girl. I really really need a girl tonight, or im going to want to shoot myself. Any advice on ANYTHING will be so appreciated.

Also, im new to this. thanks alot!

Don't go out being needy, girls will pick up on it straight away.
Imagine you have four HB10's on the go but they're all out of town at the moment. How you would feel if that was true is how you should act.

Dude I heard that thing called PUA helps a bit. Maybe you could look at any material ever to help you?

But if you want serious advice now.

Youre already starting out bad. Your mentality is all wrong! Youre going out cause a breakup, your not confident (dont fecking argue with me, from what little you wrote you dont radiate self assurance) and you might come off as needy
Already youre caring too much.

Instead why dont you gather a few of your peeps (Unless you prefer do to it alone), go to your local hotspot and mate, JUST HAVE FUN! Enjoy yourself! Put yourself into that mood.

Then go start talking to girls! Itl be easy if you stay calm and self assured. And if your stuck on what to say, check out anywhere else on the godamn forum! Do your research mate!
