21, found trp a few months ago, started eating right and lost 20kg but still a bit chubby. I started building up my confidence as much as I can by "Faking it" until you don't have to. As I thought I finally had some confidence that was not "Faked", the cruel reality hit me in the face like a shovel at Mach 3.

At the end of my shift as a waiter where I work for about 2-3 months, most of the staff sits around for a beer or 2 having some laughs. Everything was going as it usually does as everyone were laughing at random stuff, deciding to make fun of the new waiter who just quit on his first shift. Until they instinctively started laughing at me, making impressions of me and actively mocking me while laughing just as always While telling me how they mock me behind my back all the time.

This crushed me from the inside and made all my so call "not fake" confidence to shrivel up and crumble to a tiny pile of self doubt.

My questions are, how do you deal with such a situation? And how do you get back up after this kind of blow to your ego?

TL:DR Group of coworkers admitted making fun and mocking me behind my back, crushed my confidence. How do you deal with it?
