hopeiwontforget1 year ago I feel the same way. In those situations, I tend to tell the person that I need some alone-time, because I know I can not talk about it when feeling like this.
Like you, I don’t hurt people, but I tend to shut down completely. I just stop talking, don’t say a word, which is so NOT me. But inside I’m exploding. When alone, I then also tend to throw things, sometimes cry, scream in a pillow… i feel like I need to wait for it to pass naturally cause I can’t control this feeling, which I hate. Leaving the situation has helped me, taking a walk. But don’t leave without saying anything, I feel like it’s the best to say you need some time to calm down and think about, and you don’t want to say anything stupid, so you prefer to be alone, calm down. And propose to have a conversation later! :) Really, going outside changes your perspective, the air helps and your surroundings distract you! Also, like others said, writing helps!! Just for structuring your thoughts. Sometimes, when I feel to angry to write, I just record like a voicenote on my phone which is really just to get it all out! Helps me a lot to calm down and start to move on or prepare for a conversation :)
Sorry this message is so long but I feel like it’s an intense topic!
