The religion prey's on anyone with low self-esteem and fuels the negativity that drive's people into self-loathing.
When is it time to disconnect with loved ones? I think if they repeatedly bring you back into depression hell", or leave your head spinning for weeks after talking to them, it's a good idea to avoid them. In the last Hall I was in, we had a couple with seven kids who had no part of the religion. They had not talked to any of their kids in twenty years, out of seven kids, not one would talk with them! I will blame this on the parents who are self-righteous and refuse to visit their grand-kids who never knew them. It's the beauty of the cult, that shredds innocent grand kids from every seeing their grandpa and grandma, don't you think?
I can only say what works for me, I avoid anyone (including family) that rob's me of my job or attempts to start touble. Life is short, big hearted people open themselves up to having their hearts ripped out, by those who are suppose to love them. I hope you can adjust your expectations with your daughters by not expecting anything from them, in time maybe they might see the "light'?
keeping busy with art or helping with the community sounds like a good way to keep the overactive mind busy! God bless you Lady Lee!
