Born in Poland and exempt from the US travel ban but... [31]
I have been trying to contact the Polish Border Guard but so far no luck.
No kidding...Contacting Polish Consulate in Chicago from Chicago is harder than reaching the White House so I am shocked that some naive soul gave you that advice.
The easiest thing to do is to travel to Poland and "kill two birds with one stone".
You are assuming that your physical presence would change things. I wouldn't be so sure.
I don't know how much that land is worth and who will get the money when sold. If it's not much or if it's somebody else who will get it proceeds, just walk away. At some point, I had an opportunity to buy my parent's apartment at one of the best locations in Warsaw (Nowy Swiat 47a) and realized that the gain would not be worth the aggravation, so I just let it go.
but she doesn't go and she doesn't take her medications.
Even if she did, she is not your moral or legal responsibility. With that attitude, you are in the clear if you just let things be. Are you going to be there to argue, lose, and feel like s**t that you didn't do enough? How long are you willing to be there? Until she dies or when you will get to the end of your rope?
Acting on emotions is never good. Think things through, have a clear "what if" plan before you take the first step.
My best advice and the bottom line: let it go. You have your own life to live.
