Hello and welcome wanderingbear.
As part of my experience with depression and trauma I too have been grossly effected by events with which I empathise even though not connected with me so from my own experience I can assure you that your reaction is not absurd nor should you be embarrassed. I agree with others here who have suggested you should find some trauma counselling and develop some methods of dealing with your reaction to events with which you identify.
My thoughts are with you and I hope we can talk plenty in the coming days, weeks, months... Please feel free to pm me anytime.
