I fell for a scam that I paid for with my mother's money
Are you serious? Why did you use your mother's money?
I was in desperate need of money.
It's too bad you fell for a scam. You shouldn't take money from your mother to pay for things like that.
I'm now planning on how to steal her credit cards.
That's awful, you need to stop stealing your mother's money. You need to earn yourself some money the honest way and pay her back instead.
