I just won't deal with it in my life anymore. I've had enough of trying to turn it around, to ignore it, to deflect it and now I have realised that eventhough these negative people are family, I have no obligation to spend time with them unless "I" want to. If I choose to, then I have to put up with the negativity but instead, I simply choose not to be around them.
I have finally decided that I will not waste my good heart and generous nature on people who either don't appreciate it or don't deserve it. I truly believe that I deserve better than that and now I demand it of myself and those I want close to me. Negativity has no place in my world right now. I need support, reinforcement and 'real' caring because that's what I give to others. If they can't or won't give back the same, then it's their loss. I got tired of twisting myself into a pretzel.
Sorry you're having these issues. Negativity is a terribly heavy state and it permeates everything and everyone. I hope you can find a good way to overcome it or stay away from it.
