The healthiest way for me to deal with it is to just go on with my life, without them. They chose to shun. They chose to be out of my life, and I refuse to grovel and beg for them to be part of my life if they made the personal choice to shun me. I will not give them the satisfaction. I will not validate their beliefs by attempting to maintain a relationship with them that they have made plain they do not want to have.
That is exactly how I feel. Most jws are so tied up with the Watchtower cult that a normal relationship is next to impossible to have with them.
