I'm so sorry about your grandma. I understand the pain of loosing a loved one. I'm so glad though that you have some wonderful memories of the time you spent with her over the years and the good things you did for her.
Try to keep those in the forefront of your mind as you work through this difficult time. It seems that in so many families, there are those who did the right thing by their loved ones in life and in death and those who are selfish during their life and death. The ones who are selfish usually end up paying the price somewhere down the line while the ones who did the right things have peace of mind and heart.
You can't control how other people think or behave right? All you can do is control yourself. Once we understand we don't have control over those who are hurtful or selfish, it's much easier to let it go and hold onto our own good feelings of the loved one we are loosing/have lost.
I wish you peaceful times and thoughts during this difficulty.
