Even if the confrontation isn’t about me, I will get really stressed and shake uncontrollably like a huge rush of adrenaline. It happens when I get angry as well and I have no control over it, after a huge argument with my sister one time, I was trembling/shaking and she was like ‘why are you shaking like that?’ She was genuinely concerned. I’m pretty sure this is a panic attack I don’t even know myself.
