First, don’t tell me that the answer is just to “not bottle things up”, because that’s objectively incorrect too. Society doesn’t want you to have any negative emotions. I need to know how to not express negative emotions at all whatsoever unless I’m alone. I know it can be done because it is done in many other people on the planet.
Yes I have very recently. It is currently an ongoing ordeal but I am not hopeful. People have gone to HR about my supervisor before and it has never changed anything.
