Support for Loving Memories and Cremation

My name is DJ Farley. For the past 4 months, my wife has been battling liver and kidney disease. She fought harder than anyone should have to, and still wasn't able to beat it. I've taken almost 3 months off from work to be with her. I only have a few days left with her and I never wanted to think about the costs and what's needed after. She had minimal wishes for after she passed away: just a cremation, a necklace for me, and loving memories. I want to be able to do this for her but lack the funds since I haven't been working. Anything will help get me towards this goal. I want to be able to do what she wanted.
