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.
Well, that’s good to hear. Hopefully it helps, and I’d also suggest that it means they do care, at least a bit.
Maybe they do need to give you more time to vent, it’s hard to say without being there. In general, we on the internet don’t know you and can’t have enough information to help you the way a therapist can.
