Financial support to help save the family home

Hello

My name is Charlotte. I am trying to save our family home. I have lived in this home for 28 years and my children have grown up in this home. I lived here with my ex-husband for most of these 28 years. He passed away in January. I am now faced with trying to buy the house myself and my children have lived in since 1996. I am in need of help to save my home. Any help is greatly appreciated.
