Emotionally unavailable mother, need serious help.

I don't want to say much.. ( energy drained).. I am so sick of my mother's behavior(cold and rude)... She kills my happiness everytime i feel.. When one day i expressed all these things.. She got defensive instead of thinking of a solution for her mistakes that i told her... She started speaking like "okay from now on we will not talk, am i rude to u right? Ok then we will not talk from now on... Also she is soooo controlling... First says yes to things..and then no(killing all the happiness).. And this is not even first time 😭😭😭..nxt yr i will move out.. But still need help.. Please 🙏
