Repeated failure

I am terrible with my finances. I ask God to help me and He does but I end up in trouble all over again. I’m Past 70 and live on a fixed income. I have had many health problems and have not been able to earn a living.Why can’t I learn to use my finances in God’s will instead of having to constantly having to ask over and over again for his help? How many times is He willing to help me out? Please pray for me!
