Bouts of Rage

So I have been having these bouts of rage for about 3 years now and they just came out of the blue with no explanation. Sometimes something incredibly trivial will annoy me and I fly into a mindless rage. It is shocking like my body will lock up and I cannot move. It only lasts for like a second or two. the only sign to someone out side might be a widening of my eyes or sometimes I wisle through clenched teeth.

Over the past three years, these have been getting more frequent and it worries me. I can't bear to tell anyone. I am incredibly frightened when I have these bouts thinking someone will notice. I have been under a lot of pressure to get a job lately but I am worried about this happening at work. I am not sure how to handle this. T
