Welcome vinman, I'm sorry that you feel so alone. You are not alone and you do have options. You just have to initially deal with the confusion and stages of grief that you are feeling and then move on to making plans how to help your loved ones to start critically thinking for themselves.
Don't rush into telling JWs how you feel or what you learned until they tell you their doubts. Learn how to ask simple questions of JW family and friends to plant seeds of doubt in them and how to overcome thought-stopping platitudes that they say like "Where else would we go?"
Post how you feel on JWN so that you do not explode your feelings on your family and to learn what options that you may have. Is there a non-JW who you can talk to about your feelings? Can you afford to talk with a counselor?
Research the Watchtower's history and doctrines through reputable websites like www.jwfacts.com, www.watchtowerdocuments.com, and www.jwsurvey.com.
Have you read information by cult-exit counselors like Steven Hassan's books (i.e., "Combatting Cult Mind Control", "Releasing the Bonds: Empowering People to Think for Themselves", and (his latest book) "Freedom of Mind: Helping Loved Ones Leave Controlling People, Cults, and Beliefs), visited his website www.freedomofmind.com, and watched his videos like Strategic Interactive Approach explained 2003 (1:23:23)?
Best of wishes making your plans to live free from the Watchtower's use of BITE manipulation techniques and using undue influence to victimize JWs.
Peace be with you and everyone, who you love,
Robert
