Hey Randrum,
It's ok to not know exactly how you ID in all ways. It's ok to just be where you are. It's ok to have a mini freak out, it's ok to not know all the answers to the questions people ask. It's ok to just say hey, I'm finding my way and I don't know right now. Hang in there, you'll find your way. And just so you know, there's a lot of us here that have gone through that in life as well, if you need questions answered, just please ask, someone will gladly repsond to you .....maybe even a bunch of us will.
Hugs to you younger brother, you belong right here with this family if you so choose to remain being part of us. Don't let any of the questions people may ask, run you off, ok.
