aprocryphal22,
I know it's hard now. And there will be more hard times in the future too. But you, out of all your family members, have been the first to "wake up." Cult expert Steven Hassan says that all cult members, deep down, want out. You have opened the door for yourself and also for your family. They may or may not walk through it eventually, but either way, you have. While it's difficult, you can celebrate the fact that you have done it. If you still have a belief in God, pray for them that they are able to follow your example and get out too. If any of them wish to, it will be easier for them because you paved the way.
In the mean time, a whole new life awaits you outside the WT. It's yours to explore. Over time, you will make new friends, find new opportunities for growth, and build a new life for yourself. I don't know how far along in your journey you are, but I speak from experience when I say that it does get better over time.
I have lost many members of my family too, since leaving, but I still don't regret doing it. It is one of the smartest things I have ever done. Congratulate yourself for having the courage to see your way out. Many never do and spend their entire lives in the darkness of that organization.
Best wishes and good luck to you.
PS - If you're still in your thirties, you're doing pretty good. You still have a large part of your life left and time to do something with it. What would you have done if none of your family had been JWs and you were raised in a normal life? Now you can do it! (I'm in my forties and I just graduated from college. Boy did that feel good!)
