Let me tell you one thing you are awesome. Go in front of the mirror and tell yourself that people are people that's it no hot no ugly just people if you get her number that means you attracted her which means .you are at the same level just two people attracted not hot not ugly just two beings. I think of it as everyone needs attention and love and passion. And anyone can give it. Your confidence is holding back your "giving" tell yourself your awesome and she needs you and you're the shit. And boom you won't be thinking about things that wil get you down or make your mind drift away towards your insecurities.
