Welcome to GSC! I remember the feelings you describe and it took awhile for me to gain confidence in my new identity, too. Everyone has a different path, so take your time. There are tons of books to read on cults, fundamentalism, etc. but mostly I'd say:
1) LISTEN really closely to your inner self, gut, or whatever you want to call it.
2) Go slow in making decisions.
3) Breathe deeply often.
4) Remember that exercise clears the mind and does wonderful things for your body/mind that no amount of "figuring stuff out" can do.
5) Be kind to yourself and others. Like they say, "We're all walking around in an emotional emergency room."
Take good care of yourself!
Be your own "cause" now.
Visit GSC when you can to gain support. We're glad to be here for you!
