The loss of my husband

Hi my name is Mary. I lost my Son 15 months ago and I lost my husband about a month ago. I am unable to work due to my mental health and physical health. I haven't been able to draw s.s from my husband, and due to that I am struggling paying my bills and sometimes putting food on my Table. If there's anyone who could be willing to help me with the struggles of now being on my Own completely with no income at all coming in.
