Sigh...honestly I don't know why individuals who can be so toxic end up getting their way and getting ahead when they don't deserve it. It's a hard pill to swallow when you have experienced their toxic ways first hand. I have faced these kind of challenges myself and certain things have left me feeling empty and have shaken my faith. I can't blame you for not wanting to be anywhere near these individuals.
I have been going through something myself that has been extremely triggering and challenging. I hear you.
