poor girl 
it must have been a horrendous experience for her - but surely they HAD to tell her the facts, really. How else can she make an informed decision?
Did she say the sonographer was hostile or nasty to her? Or is it the facts that have upset her?
I had a sonographer upset me badly one, I was bleeding at 10 weeks and was called in for an early scan. I was so relieved at seeing/hearing everything was OK, I asked for a scan picture, and the bitch said "Don't tempt fate - I would go home and pray if I were you"
but if you weren't in the room, you can't know whether there was any cruel intent or whether it is just the enormity of the situation and the brutality of the facts that has upset DSD
