I'm going to spend my parent's money like water and feel guilty
Why are you going to spend your parents money if its going to make you feel bad?
I feel like my mom is doing nothing for me, She's cooped up in the house.
It's wrong to take advantage of your parents financially. It may be beneficial for you to talk with your mother about what you need from her at this time.
I will do what I want with my mom's money.
Spending all of your parent's money is wrong and will have consequences for you and your family. It would be good to consider what you really need at this time. What void are you trying to fill by spending money?
