It sounds like you’re going through a lot and you have a lot of courage to post your background here. I don’t think I would’ve been able to do the same.
I just wanted to let you know that I’m also an FFS and can relate to the unique difficulties we might have.
I’ve found that having 12 years of Day School education helps immensely to function in a frum community, I’m familiar with a lot more things than a “typical” BT.
At the same time, while leading my family to become more religious has formed my personality and made my unique and interesting that my FFB friends don’t share.
You probably feel a lot of anxiety and uncertainty. I wish you luck finding a posek that you trust who can also help look into the logistical details necessary to answer all of your questions. I wanted to let you know that you’re not alone and that others also have their issues to deal with.
