For starters, I'm 18, 140lb and 5'10", which I know is an average height, but everyone around me seems to be over 6', and it really bugs me

Everywhere I go I feel like a little kid and it fucks with my frame so much. I just feel inferior to people that are taller than me.

Before you ask, yes I lift, and am trying to bulk, and I do BJJ on the side
