When I have really high anxiety or someone around me is sick....sometimes I go from being really scared to really really mad at this whole situation and can be mean to whoever it is that is sick. I think it's because in those highly stressful situations the only thing that can help me feel less scared is just being angry at sickness. I can't become calm, I'm already sad and scared...the only thing left I anger. Anger is a second emotion. So my fear causes anger....if that makes sense.
