I'm going to ruin my mother's life
Why would you do that to your own mother?
I have been rude to her and now she keeps punishing me for it.
It is never too late to change. Your mother will appreciate if you stopped being rude, and less people will be upset with you.
I've never in my life received help from my mother, now I'll get her to pay.
Revenge is wrong, other people can see how you act and they won't be on your side. Ultimately you will lose in the end you know she can have you removed from the home if you do something so crazy right?
