sounds like your parents are travel agents for guilt trips. when i first began reading the letter, i thought perhaps you did something seriously wrong..drug addiction, murder or homosexuality. what a terrible decision they made and your right, so unnatural. you should of never been put in a position. my two adult children left in their late teens and i never could of quit talking to them. that's one reason i'm not a jw. the only difference between you and those going to the hall is that you are choosing not to live a lie. isn't it interesting that they would be happier if you did though?
God Bless and BIG HUGS. This would be like experiencing the death of both of your parents. How SAD for you and them both. I'm praying the tides will turn.
