Hello Jules,
I can relate, my Mother told me the same words, almost word for word as your post and we haven't talked in a few years as a result. How I personally was able to get past it was just recognizing it for what it is - MANIPULATION. The number one way to control someone is through fear and the organization has mastered this concept. It is hurtful to hear those words, however, once you realize it is a scare and control tactic it will be easier to deal with in my opinion. Just pray for those family members that have told you that and realize that is them that are living a life full of fear, while you have moved on and living life without fear. It wont take away the hurt, but it will be easier to cope. Hope this helps.
