When my mum asked me will I go to the convention, I thought "No way", and that's my answer to your question.
Maybe there were times when I thought I was happy as an active Witness, but I don't think I really was. How can anyone be happy being an active witness knowing the truth about the WTS, their hypocrisy and how many lives have been ruined due to their teachings?
The problem is knowing what I know now is not making me happy either. I feel like everything has been taken from me, being raised as a witness, I never celebrated anything, never had close "wordly" friends that I could turn to now, and my family and friends feel sorry for me as I am "spiritually weak". I can finally understand how those people felt who were standing at the exit of the convention arena.
