Welcome DuvanMuvan, Are you still living at home? What are your plans to become financially self-sufficient to reduce being pressured to get dunked? As long as you don't get dunked, your family may not shun you in the future - NO gaurantees though.
Although JWfacts is an awesome website about the WTBTS, you may want to visit www.freedomofmind.com to help you learn how to communicate better with JWs so that you can avoid being shunned. Reading Steve 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"), visiting his website, and/or watching his videos, should help you communicate better with JWs' authentic personas to minimize the possibility of being shunned by JW relatives and friends.
Peace be with you and everyone, who you love,
Robert.
