Welcome! So far, pretty much everyone I know in recovery has had a case of "terminal uniqueness", myself included. I can only speak for myself, but that "unique" feeling that I'm the only one who's ever felt this way is just my good ol' alcoholic brain trying to edge me away from the good life again.
Good luck! Great group of people here. I did a lot of reading here when I was first starting to sober up, and it REALLY helped!
