I have the same issues. Never knowing when the anger will strike or who I'll take it out on... Therepy helps!!! My therapist has given me tools to disengage my emotional brain with my logical brain. As I feel the anger coming on or I wake up angry I start to think about how bad is the event that is causing my anger. On a scale of 1 -100. 1 being not a big enough deal to even register and 100 being the whole earth and my and my family lifes dying the most horrorifying painful death known. Each point in bewteen is rated a little harsher than the point before. So I try to figure out on my scale this issue rates as far as a response from me. By the time I figure out where on the scale it is my logical brain has taken over and it represses the adreniline and starts to calm me and I can rationaly look at the issue and give it a proper response. Since I've been doing that I haven't had an angry outburst, where before I would tear someones head off just for leaving a dirty glass outside the kitchen. I hope this helps. Get to therapy and maybe your therapist can help oyu find ways to dissolve the anger before you react to it.
