Karla,
I'm so sorry your husband is ill and you have no one to help you care for him. I know it's hard because I had the same situation when I cared for my husband who died of lung cancer in 2024. His children were from another marriage and never visited him before he died. He was 83 whwen he died so all family members were already gone as were close friends. What really helped was prayer. We prayed everyday and God was there for us. My husband lived 14 years with stage 4 cancer. I am so glad that we had those last years together! I miss him terribly but God is here for me. Just ask God for help and you and your husband can get through this difficult time. I'll say a prayer for both of you also.
I wish you the best.
