I think I'm going to be rude to my mom.
Why would you be rude to your mom?
She always talks trash about my life and my friends and she constantly tells me I'm heading in wrong direction.
It is unfortunate that your mother views you in that way. As a parent, she should be helping you out and providing support for you, not putting you down.
I'm no longer going to listen to her and I'm sexually frustrated.
It's not right of your mom to put you down, but you should also try to be respectful of her. It's possible that she's a toxic parent, but it may also be that she's trying to give you real advice. Only you can decide which it is, and if you need to make a change for the better.
