Welcome thewalker, I do hope you give yourself time to think through all the signals your mind and perhaps body is giving to you that indicate something is "rotten in paradise". I had thoughts I dismissed for years as just me being a poor witness, I finally had to confront the real issues, did I truly believe this was the truth, could I accept the changing doctrines etc..
So take your time do not burn all your bridges at once, take the advice given regarding education etc. You are such a lucky young man to wake up so early and not have to waste the rest of your life as many of us have done.
Best wishes Chicken little
