I took my mom's change and donated it to charity.
Did she tell you to donate it or did something else make you do it?
I did it because she screams at me for everything.
It must be difficult to deal with a mother that gets so angry, but donating her money without her permission isn't correct. Address your mom's behaviour when she screams at you instead of being passive aggressive.
You are not helping me. I'll find my own way of dealing with this.
The best way to deal with this would be to apologize to her and to talk with her about how she is treating you. Stealing from her, even though you did a good thing with the money, is wrong and will just make her more upset with you if she finds out.
