So this guy knows me since my childhood. I'll admit it, I was stupid asf at that time. I really admired this guy and everything he said to me, I took it as criticism to improve upon. But now I just feel like he's just making fun of me. How the hell do I stop this?

This is not the end of the story, I feel so weak in front of the people who know me personally. Whenever they make fun of me, I can't do anything else other than just smile.

It's gotten to a point where I hate to see my stupid smiley face in the mirror.
