I understand it must be really difficult and painful to feel unappreciated and to not get the love and attention you want and need from your family.

That being said, given your prior post, you are doing SO well in life -- SO WELL! Professorship at a prestigious university, you own your own home, and you came home to help out your parents (which is MOST admirable!!). Sometimes we have to validate ourselves when we don't get it from others that we care about. You are doing right by your family... and that is the honorable thing to do. Your sister sounds a bit less self-reliant and self-sufficient, and perhaps even a bit more selfish since she is not helping. I wonder if your family sees you as the one who is doing well and her not doing so well and that's why they give her more attention? I could be wrong, but it's a possibility. And then there's the unequal treatment towards your former partner and her fiance. That's not right....

My hope is for you to somehow make peace with this situation, as best you can under the circumstances, knowing that you are doing the right things AND that you are secure in your own life and are doing so well.
