Just like anything else in life, you have to do this step-by-step.
First, don't sell yourself short. You have some valuable attributes and characteristics that others will find valuable. You find a friend or group of friends who are a notch or two closer to where you want to be, people that have something valuable to give you and to whom you can give something back.
You slowly replace your friends with "better" ones that will bring you closer to your goals and will make you more of who you want to be, and you climb that ladder to the top. It'll take time, but it's also a far more guaranteed outcome versus suddenly jumping into a circle you don't yet belong in, where even if they'll accept you, chances are you'll change your mind and back out.
