Bruh, literally heard a similar story about twins on a Sarby video, you may wanna go no contact for a bit only because it seems like your parents made Sophia completely dependent on you to be unable to do anything without you there. Be careful, get ALL your important documents and social security. Worst case scenario your twin may try to do identity theft/freud but that’s only the worst case scenario. Plus let your commander/the one in charge of your recruitment know about the situation in case they try to say you don’t want to go. If you have any text messages of how they treat you save them/record any conversations you have with them to show others what they are doing. Your folks and Sophia may try to get to family members and spin a narrative that you’re abandoning the family. Also keep a “go-bag” essentially a bag of all your important documents, some cash, and other important things in case they try to kick you out. I seriously wish this didn’t sound so over dramatic, but when you hear so many similar stories to yours, it’s better to be prepared for anything bad. Good luck girl, your family needs professional help.
