Ann25,
I learned early on that when people speak to me the only thing I control is my reaction to whatever they say. If they speak to me in a way that's unkind, or attempt to manipulate me or my emotions for their purposes then that is their problem and not my concern. It's between them and their Higher Power. I have found it useful to say a prayer when this happens, something like: "God, I believe I was treated poorly in this instance, but that's between you and so-and-so. I pray for them, that they may know your will for them and receive the power to carry it out. Please take my hurt feelings, God, because I can't handle them. Thy will, not mine be done."
I can also choose to pick up someone else's burden or draw a healthy boundary and enforce it in a loving, compassionate, healthy way. Hang in there and do the next right thing.
