Final expenses

My wife of 13 years pasted away yesterday morning. She was only 35 years old and went unexpectedly in her sleep. Now my 12 year old daughter and myself are trying to figure out how to pay for her final expenses.  I have allready began selling my belongings because getting her handled has to be taken care of right away. I have never used one of these sights before I do work a job I just have no money saved at this point. I have never felt left so alone in my life!
