Though I am not a religious man myself I find it extraordinary that you should lose your faith over a natural disaster. It appears to me to show a lack of maturity to throw ones teddy in the corner because God has been unkind by sending a tsunami to cause havoc on Boxing Day. After all, natural disasters are part of Earth's history and it will continue to be so.
I watched my mother die very slowly of cancer and it has had a permanent effect on me but although I do believe in a creator I wouldn't say I blame God for the many afflictions the human race is forced to endure.
I rather suspect that your loss of faith was due to a collective body of things that had accumulated over some time. Certainly the Watchtower has had its effect on all of us which doesn't help at all because it fills people's heads with idealistic ideas among other things.
Nowadays, I have a much more pragmatic approach to life.
I wish you well Cofty.
