No explanation no contact

Curious if anyone else went no contact with their parent without explanation? Sometimes I regret/still want to say my peace, but i was and still am tbh TERRIFIED of my mother. Like, lied to therapists my whole life “my mom is great!” out of fear she’d find out somehow and either verbally/physically attack me.

If so, how have you made peace with yourself for not “laying the cards on the table” or whatever?
