Recoup Memorial Service cost

My son's father passed away, due to a heart attach, on Oct. 1, 2020. It was unexpected and I, their mom, was left to set up a service for him. I am trying to raise money so I can help pay for the costs of putting things together to give him a service and my son's closure. We weren't a couple in over 10 years and he had no pre-planned way to pay for his death expenses. I purchased flowers to make sprays for the table and made pictures for the service. Any and every donation would be greatly appreciated.
