Congratulations, Dubstepped. Welcome to reality.
You have already been provided with great advice from other posters. The following is what I wish I could have said to myself when I walked out:
"The next few years will be scary and exhilarating. There will be LOTS of things you will learn but, more importantly, unlearn. Soak up all of the knowledge, freedom, and experiences you have been denied for years. Take every opportunity to educate yourself on everything from critical thinking to science to politics to religions and myths to social sciences and on, and on... For the past few years you have not been thinking for yourself but instead blindly following orders. You will not only need to learn facts but learn the skills to think critically to evaluate them properly.
QUESTION EVERYTHING! When you were in you were absolutely convinced you were right on just about everything. You may find that you are wrong on just about everything you believed and still believe.
Stop believing that the Organization (or JW family) have the "moral high-ground". That is purely an illusion. You will find better people and friends just about everywhere else.
And, don't be afraid. You will never be alone."
