Convents and Sisterhoods

Okay, so:

Just as a thought, I have considered devoting my life to God and becoming a nun.  Part of the problem with this is that I have no desire to convert to Catholicism or Buddhism.  There is good news though, there are indeed protestant convents.  Again there are problems, they are all orthodox denominations: Methodism, Lutheranism, Anglicanism, etc.  Being part of a Christian church, and no, not DoC, I don't really want to convert per se.

So, here in lies the problem: should I decide that this is the path for me, and I'm not 100% sold out, I have nowhere to go.  I could make the vows on my own to God, and I believe that they would be binding and honored by God, but not by man.  Oh well though.  Just a thought.
