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.
What about your friends or family? Particularly in some countries, it’s true that public displays of unhappiness are taboo. Less-than-totally-public displays are kind of a huge part of people’s social lives everywhere.
Friends and family will either listen to a point before saying they can’t handle it, or some of them I wouldn’t bring these problems to in the first place. When I do talk, I get tired of my response being the thing they focus on instead of the source causing my frustration. I’ve attempted therapy for years with varying success; after some bad experiences I can’t trust therapists anymore. All anyone cares about is if my emotions are impacting them in a negative way, nobody actually gives a shit about how I am doing as long as they aren’t directly inconvenienced.
