This is a very morbid question, please don't judge me or don't read if you're faint of heart?

One of my best friends boyfriend shot himself sitting next to her yesterday. Everyone is keeps saying they're praying for her and they're so sorry she is going through that and how unfortunate which is what I've been saying too but I can't help but want to jump in her head and understand what she saw, what she's feeling right now. Why do I keep doing a play by play beak down of what happened in my mind instead of just accepting that he did this and get to comforting her like everyone else. She won't talk about the details yet but all I can see is her sitting (or lying) there and he's telling her how he hates his life or maybe how he loves her or ranting about something and just says some last words and blows his head off. Or maybe she was sleeping and woke up to a gun shot. I keep wondering what happened next, did she get covered in his blood, did she scream and run away or did she grab him and try to see if he was still alive? Did she stay in the same room with him while waiting for the ambulance? Then watch them take him away? I don't know why I'm thinking about the gorey details but I guess I want to get in her head to see what's the best way I can help. Please don't judge me, I don't know why my brain is trying to dissect everything. Does every one think this way and not say anything about it or is it just me?
