I make my mom's life much harder than it needs to be.
How do you make your mom's life harder?
For example I once shut the door so she couldn't open it when I was watching TV, I've stolen all her cleaning supplies, clothes and shoes.
That's terrible that you treat your mother that way!  You shouldn't be so awful to your parents.  They spent a lot of time and effort providing for you!
I guess, but I think my mom should be better and understand that sometimes I want to use her things.
I'm sure your mom would let you use her things if you asked, but stealing them is just wrong. You should really treat her with more respect, or she might not be willing to help you out if you need it.
