help cremate my mother

My mom meant the world to me. In February she passed away suddenly of what I can only describe as a massive heart attack on the back patio of our home in the middle of the night. We live in Michigan and she was not found until the next day. The medical examiner told me that fortunately she did not suffer from frost bite. My mother was diagnosed with stomach cancer in May of 2003. She had smoked most of her life and as a result had severe heart and artery problems in addition to the cancer. She was 61-years-old with a lot of spunk and an infectious laugh. She had been married to my father for just 14 years at the time of his death and together they had three girls. She loved people and staying active until his passing, then she mostly stayed to herself and tried to look after us girls. We had lost contact for a long time until she reached out to me, I offered her a place to stay as she brought her health issues to light. She attempted to follow the doctor’s suggestions on three occasions with horrible results. After her first round of medications, she suffered dehydration and her bowels became severely impacted. We discussed her options openly and agreed to discontinue any further treatment since the cancer was slow-growing. However, her heart problems still plagued her. During the next 2 years she helped me us much as possible with my daughter and around the house as much as possible. She loved being a grandmother and spoiling my daughter with love. She didn’t have much money, surviving only on Social security, but she spoiled my daughter in so many other ways. She attended all my daughters school functions even though she was unstable on her feet and required a cane. She didn’t want to miss a minute of that time. I feel I have no one that understands where I'm at. I was the one at the very end of my mom's illness, trying to help her get things together. We had talked often of trying to get her some life insurance but never had a chance. My sisters are not in any kind of position to even offer help. So I turn to you to help me with bring closure to her chapter.
