If you are dealing with the recent loss of a parent, please reply?

Hi, I recently lost my father, he was young and it very sudden and untimely.My father was healthy with no major health troubles. Im a doctor myself and this has left me with a lot of guilt, and grief. I just cant seem to stop thinking about him, I cant sleep and feel numb most of the time. I just cant seem to find any answers. I feel noone( including a therapist) can understand what Im going through, unless they have experienced such a profound loss themselves. I would love to hear from you or even correspond via email if you feel the same need to talk your feelings out with someone who understands
