I'm feeling really ___________ right now

STRESSED and annoyed. I want my brother to just leave me and my mother alone. I’m so tired of him calling the house. He’s an addict, a narcissist, a manipulator and just an all around nasty person. I have given him so many F******** chances! It’s like I’m out here taking care of our disabled mother alone. I have ENOUGH *kitten* to worry about! I’m already spreading myself too thin. My mom just keeps feeding into his narcissism and emotional blackmail because of guilt and she’s trying to pull me in with her. He is NOT dragging me into his toxic world of chaos. I don’t know how many different ways I can say that I want nothing to do with him. He. Just. Doesn’t. Stop! I’ve always put everyone’s else’s needs before my own and I’ve suffered for it. I’m just so over it. I just want to live a peaceful life already. He’s never going to change and I am not obligated to help him. He needs to grow the hell up.

Now I can’t sleep. I wish I knew how to remain unbothered.
