It is frustrating as you are correct in that the only people who get it are those who have PN. It is a lonely journey. Marriage becomes a rather depressing endeavor when dealing with PN as well. I love my wife and am very grateful to her. I will never be able to repay her for all she has done for me. I fear her repayment in life will be to witness and care for an increasingly debilitated spouse. That's been very hard for me.
