Yeah, I mean, living in a monastery is a huge commitment.
I don't know how long you've practiced, but, I'd talk to a teacher rather than folks on here. I mean, there could be some random chance that one of us stayed in a legit monastery, but, I'd start with talking directly to a teaching at a Zen or meditation center in your hometown (if you live in a big city, at least).
That'd be a good start, in my opinion.
