Support for Grandma's Cremation n Costs and medical bills

My lovely grandma died in her sleep. My grandma was not sick or anything; she was an 82-year-old beautiful lady. Money is an issue to help with cremation for my grandma. She was a loving and caring woman. She loved to shop, visit family, drive her car, and was always a worrywart. She had a great last Christmas, and I'm glad she was not alone and passed with family around. If you could help her kids with this, it would be appreciated. My dads on disability so he dont get much money to even live on and cant work due to cronic pain. So anything helps thank you all.
