Caspian,
You're in for quite a rough ride, but, such is the price of freedom.
The only advice I would give to anyone in your position is to get yourself quietly into a social scene where you are not judged on your religious beliefs. Anything at all is good, art classes, keep fit, a part-time college course learning about something that has always intrigued you, even working as a volunteer on a preserved railway. A spirit of cameraderie soon develops, this is based entirely on what you are, as opposed to what you do and what you believe.
