I'm so sorry to read about the way your family is treating you, but I must say that I completely understand it. My brother and sister just don't have a clue as to how I feel. To make matter worse my sister works on an ambulance helping people all the time so you would think that she could be sympathic to me. NOT!!
I just continue to talk to them, send them cards, but I don't let myself get upset anymore about their lack of understanding. I just don't have the energy for it anymore.
Keep your chin up and I praise you for being the better person.
