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.
Edit: Ok so I think one of the things I want to try doing next is ask for a med change from my psych provider.
I would say therapy and find a healthy way to offload steam such as exercise or meditation or walking your dog or hitting a few balls at the driving range…etc you get the idea.
Regarding therapy, if you want to explore that it may take a few tries to find someone you click with but I have many friends who swear by it and say it was one of the best things they have done.
