Hello Seddit. In childhood and early teens, I was a socially awkward, pudgy kid. However, I immediately broke out of my shell in college and after graduation became physically fit. The problem is, whenever girls come up to talk to me, even when they show clear signs of interest, my mind immediately warps back to the socially awkward childhood and screams "ABORT ABORT she doesn't like you!" So, I politely end the conversation with said girl(s) and walk away. How do you overcome that negative voice that prevents you from being a normal fucking guy and actually be comfortable around the opposite sex?
