For me, when I get scared I start to get angry. I think fear is anger. I use to take anger management and it helped some. Try not to even think about that stressor. I used to do that a lot and it got worse. No, not an easy thing to do but it's helped me to cope. For me, I don't usually do relaxation techniques. When I get angry, I have found that doing something physical like running helps me calm down.
