I am lifting your mother before the Lord and I am lifting you too. Do not think your own prayers are too small. Prayer is not a last resort. It is the main way God's help enters a hard situation. The people who really accomplish anything for God are the ones who pray. Your prayers rise before him, and they are heard because of who he is, not because of how strong you feel when you pray. At the same time, you are right to ask others to stand with you. That is not weakness. Moses needed Aaron and Hur to hold up his hands when he grew tired, and God used their support as part of the victory.
I do not know every detail of your mother's illness or the financial pressure you are under, but nothing about this has caught God by surprise. He cares for his own. He is able to provide for what his people need, even when the path is not visible yet. Ask him for wisdom about the next step. Ask him to raise up the right help. Then leave the outcome in his hands instead of carrying the whole weight alone.
Jesus said, Come to me, all you who are weary and heavy laden, and I will give you rest. He did not say the troubles would disappear immediately. He said he would be with you in them. The burden of trying to make everything work in your own strength is crushing. The burden he gives is different. It still requires trust, but it is carried with him. In the times you feel most desolate, he is there. In the times you feel most forsaken, he is there. You do not have to feel his presence for it to be true. But you can ask him to make you aware of it.
Let me pray with you now. Lord, you see this mother and the one who loves her. You know the years of suffering and the weight of not being able to afford the care she needs. Have respect to the prayers going up for her. Bring help. Provide the resources. Give wisdom and open doors. Restore what has been lost to these long years of illness. Let your presence be real in their home. Lift the heaviness from the one who feels lost, and replace it with your peace. In Jesus' name.
You are not alone. Keep crying out to him, and let others keep crying out with you. He hears. He is at work even when you cannot see it.
