Getting treated like there is something wrong with you just for being quieter

20m. In my internship, a coworker who is 20-30 years older than me called me out in front of others, saying I was too quiet and bad at communicating. The way she said it was very rude. To make it worse, she and another coworker started giving me a nickname related to being quiet. I had only been there for a week, so of course, I was a little bit more observing and not so active, but I still tried to engage with the other people there by doing small talk and asking questions to learn more about the job and get to know everyone. Afterward i even asked another coworker i spend the most time with if he thought I was too quiet aswell, He said he doesn't think that way. The way they treated me caught me really of guard because i thought i was doing fine. it brought back some old insecurities and maybe even traumas I’ve had about being made to feel like there’s something wrong with me for being quiet. I try not to Dwell on it too much but it really hurts if other give you the feeling there is something wrong with you or you have to change as an introvert for being more quieter.
