One evening last week, I was listening to a programme on Radio 4. It featured a forensic pathologist who was talking about death. I joined it halfway through and it all seemed fairly innocuous and interesting enough listening while I was pottering in the kitchen.
Without warning, the woman started talking about some work she did out in Eastern Europe around 30 years ago, following a massacre involving women and children. She went into quite some detail about what happened and the work she had to do.
It was absolutely horrifying and I have found it incredibly upsetting in the week since. At the time I didn’t cry but the following evening I had a totally uncontrollable crying episode in front of my husband 
Ever since, it keeps coming into my head, very visibly. I can be fine and then suddenly there it is and I feel floored and devastated. I know it sounds like I’m being dramatic but it has affected me really badly, I can’t stop thinking about it and feel upset all the time. Please can anyone recommend any way I can work through this
