Skepsis,
Your depression is the sign that all is not well...
Cognitive dissonance seems to be what you are experiencing. Not at all easy to cope with.
You are now up against the peer pressure that an organisation like the Watchtower puts on you. It's going to be hard to break from without feeling like a bit of a 'Judas'. So the 'fear of losing everything' that you are feeling right now is quite normal.
It's great that you are feeling relieved, but you are a long way off of attaining total peace of mind, and to get there is quite a journey.
Getting a career and making friends outside the congregation is a very wise first step.
Don't be in any rush to make changes. As time goes by it will become evident as to where your future lies.
And keep posting.
