I am very sorry what you are going through, my situation is all my immediate family shuns me to a certain extent, it hurts, I haven't associated with any of my immediate family for over 2 years, sometimes I run into family like in a grocery store and they still talk to me but my dad said that I am not allowed to go over to their house and visit, I can feel your pain, it hurts beyond anything I have had hurt, its even more worser hurt then a girlfriend breaking up with me.
There are several things I have done to keep the hurt down and over time I am healing, I have for one thing found my own path in life, for one thing I workout now which helps out alot, I go to either the YMCA or I bought a bicycle and ride it on bike trails, also for an interest I have taken up dancing and have discovered that dancing is one of my passions, one other thing I do is I have found new friends that I consider family, also keep this in mind everyday that things can change, you never know when your friend will wake up, I look foward to the time when some of my family members will wake up and I look foward to helping them out of the cult.
