May the Lord make your mother well again, but please learn from this situation, and start to plan for your life as an independent person, while your mother is still here, not after the leaves this world. You are already an adult that should had been on her own two feet long ago. Sorry to tell you this at this time, but I've seen many women who their husband left them and their children, they had nobody else to help them but the Lord. They turned to God and allowed him to guide their steps to where he wanted them to be. I was one of them, and thanks God here I am in my old age praising Him for the love he has for us and for being always there. Turn to God and give him your all and he will turn your sorrows to joy. I never finished high school and had never worked, but God led me to a good paying job with benefits. Use whatever talents you have to be able to find a good job. I was strong at math, so I was able to find myself a job where I worked for a company in the accounts receivable dept. From there I became the supervisor of that dept. I was able to work there for eighteen year. When I found a good man who married me, and I continued working to make sure I remained financially independent. If I did it and many other woman have done it, so can you, have faith in yourself with God's help. It's great to work and feel good when you accomplish a days work. I always felt whatever job I did, I did as for the Lord and never allowed whatever happened or I heard around me in the office to affect my job.
Lord help this person to see your light in their time of despair, guide them to a better life. Heal her mother and may she be able to come back home to her family. Have this woman start looking for a job, help her find a good paying one with good benefits. Comfort and strengthen her as you give her your peace. I pray this in Jesus name amen.
