First off, I would like to say I'm terribly sorry for your loss.
I advise that you try not to think about it so much. I understand that it is scary, and even traumatizing, of the thought of your grandfather committing suicide and your grandmother passing away in a car accident, but you need to understand that they are in a better place. Your grandfather is now with your grandmother, and will be happy together.
If you feel bad, talk it out with your mother and her fiance. She is going through the same situation, and it is probably even harder for her.
My condolences.
