Dude you need to overcome it, otherwise you'll have many problems in your future social life.
I had all these problems a year ago and i figured it out. I knew that i have to change something in my life and i did it, caring about other people is a bad thing to do. Don't give a fuck about people, care about yourself. Why would you care for someone who doesnt care for you at all.
Also go straight in if you wanna talk to someone you know, no need to be shy. Everyone is gonna get jealous from you if you become the real alpha.
It's your life, who cares about what others think. Just do the thing you want the most, and good luck my friend :)
