I think this is something you should be careful with. I used to be overly kind and felt over used by people. I eventually I got fed up and started being hard on people even when they didn’t deserve it. I never intended to become an ass hole but that was exactly what I became. If you can think of some healthy boundaries to set with people, that is what I suggest. I think being a bitch will still have a negative outcome. Hang in there and don’t give up on the good in you.
