Grandfathers Funeral

My grandfather passed away this week and my grandmother is having a hard time with it financially. Having financial problems during a time like this is the worst. I wish I could help her personally but I am a college student with 3 kids and am fighting bills as it is. My grandmother asked me for help and I had to turn her down and its horrible. Her and my grandfather raised me and I am pretty much the only family she has at this point so there's no where to turn. She has next to nothing with her fixed income/retirement. So I was hoping I could raise a small amount to help her with funeral expenses to help ease her pain. It won't take care of her sadness from losing her husband but it will help the stress from it all. Please only give if you can truly afford it.
