TOXIC people SUCK!
Why do we continue to allow toxic people to suck the life right out of us?
That's the deeper question to ponder.
I, myself, have developed a zero-tolerance policy for these kinds of people, and as soon as I see they're trying to sabotage my process, I limit my contact with them or remove myself from their presence altogether.
This includes family too.
I simply don't have the time or energy for this kinda BS anymore.
