I'm going to ask my parents to stop making me pay rent
Why are you paying them rent money?
They want me to pay rent since I'm an adult, but I pray for mercy and will help with the bill after my new job.
I understand that you feel a need to become more financially stable. Perhaps you can explain your financial situation to your parents and talk to them about paying a little less until you have your new job.
I want to contribute to bills because I am not a child. I want to be a productive adult
It's normal to contribute to rent and bills once you are an adult, even if you are living with your parents. However, you can always talk to your parents, they may understand your situation.
