Fear of Violent Death

Hello, when I was a child I was physically abused. For many years, I didn’t even realize it was abuse. It sounded really dramatic to me, and I was only hit inappropriately (like punched in the stomach by my father, other circumstances that were similar) a few times. I realize when I look at them they were in fact abusive but since it wasn’t any every day occurrence I never categorized myself as an abused child. It seemed to me like I was making more of what it was. I think what I am dealing with now is related to this suppressed childhood. I often dream that I will die in a plane crash —I am terribly afraid of all turbulence when I fly and can almost not travel— or when I am home alone with the kids I fear that I will be murdered. I can barely sleep. I am hoping I can get some help with this. TIA
