"I feel like I am cutting anchor and drifting on an unknown current,"
It's important to understand that you have been conditioned to feel this way. Your model of reality has been twisted. An impression has been planted into your mind that inside the JW organisation is safe and outside is bad.
It is a lie.
You have accepted the lie, just as so many other intelligent people have, not because of a failing on your part. It's not because you're dumb! Smarter people than you and I are Scientologists, for example, believing things that are even more at odds with reality.
If a person is isolated, as JW's are, then a filter can be introduced between that person and reality. Everything they perceive is processed through the filter. I was out walking with a friend once and I pointed at a hillside and said "look at all those beautiful bluebells" to which he replied "What are you talking about? There's nothing there." He was wearing glasses with blue tinted lenses and he actually couldn't see the flowers! (True story).
It has become my personal mission since leaving the JW's to remove all the filters and get as accurate a model of reality as I can. One thing that I can say is that it's not easy but, in my opinion, it makes life worth living.
