Not knowing how to deal with mocking ? If your response is sobbing then either your parents failed at providing kindergarten life lession or you're so insecure that a random tweet from some dude on the internet can make you cry.

To simplify :

- I'm a professional who gets shit done, some sarcastic tweet about something I didn't know is just an insight + a hint that the person making the comment is a dick. I'm aware that despite me not knowing everything I produce valuable solutions and any solution can be picked apart by some criteria.

- I'm a novice and am aware of it - someone mocking me for not knowing something doesn't make sense - I'm not supposed to be at the level to produce ideal solutions - getting things working is an achievement on it's own

- It hurt because I'm insecure about my ability. I need to work on my ability and confidence (which is why mocking people who can't do anything about it is exceptionally pathetic).

Mocking aside - working with insecure emotional people is a chore - you have to walk on eggshells to avoid breaking frail egos by pointing out their mistakes in a way that will not trigger their ego defense mechanisms and go down that spiral.
