So sorry, Scary21, no child deserves to be unloved. This religion is a very dark one, that does not "build families up" but actually, tears them apart.
Do not think less of yourself. Hold your head up high, be proud of the fact that you no longer participated in carrying out the commands of the GB. It's not "going to 5 meetings" "Field service" and "conventions" that make you a good person.
As you can see, it is what a person does, who they are that is important. "Actions speak louder than words."
People's worth should not be measured by time on a time sheet, not "loyalty" to an organization.
Love.... "all you need is love."
Hugs to you and your sister.
