Ever heard of the saying, if you have nothing nice or helpful to say, say nothing at all. You probably lived all your life in a bubble of a loving and generous family.
Surprise! Everyone else doesn't have the same experiences you did. Relatives can be manipulative, greedy, abusive and take advantage of you for no fault of your own. Grow up, learn to have empathy, instead of schoolyard insults befitting a kindergartener.
@OP: I am so sorry for what has happened to you. I have manipulative relatives and know what it is like. Hugs and hope it ends well for you! I would strongly suggest getting legal help, since the way it looks you could end up in a world of trouble.
