Emily, I can't find the words to express how I am feeling right now. My own dear sweet dad died, not of an accident, but it may as well have been...he had a massive heart attack that killed him instantly ~ 12 years ago, and I am still not over it. His death rocked my world so much, that I ended my marriage & although I am grateful for where I landed...sent me on a *ride* that I would rather not have taken. I miss him to this day, and in an instant can bring back the exact moment that I got *the call* regarding his death ~ and all the feelings around it.
The good thing is that I got through it. The going through it was too hard for words to express, but I came out of that dark decade a better person.
Give yourself time ~ and it sometimes takes a long time ~ but try not to make any rash decisions. Feel what you need to feel ~ but don't feel guilty. Celebrate the life he had, and the inspiration he was to you and your family. Don't let his death paralyze you...let it inspire you...

love and prayers~~J
