Liz,
I am so sorry that the video upset you so much but hopefully it will prove to be a cathartic experience and allow you to release all those pent up tears and emotions you've had since Robin's death. Bottling up all that grief inside is not good.

You may find that other events trigger a similar reaction. I never cried when my father died. He had had a stroke and never came back from it. He was in miserable pain and bedridden for 11 months so his death was a blessing. A couple years later, I was sitting in the opera house when the orchestra struck up my father's favorite overture. I broke into uncontrollable, unconsolible tears and simply couldn't stop crying. After it, I finally felt like I had said goodbye. Hopefully your traumatic experience will help ease your grief.

Take care,
Eileen
