Welcome NinaCee, thanks for sharing your story.
Losing your entire extended family is going to be a blow no matter the reason, my heart goes out to you. Even though you know you could never stomach going back it's always going to hurt a bit being separate from your family. I hope you keep trying to make new friends though. The reality is that friends do come and go even without the complications of the religion, I have lost friends myself a few times do to job changes, moves, etc. Being an introvert and not working anymore it's hard to make new friends these days, so I can relate to what you are going through.
