Rob hang in there, think about the other times you have projected gloom and doom in the past and you were WRONG!!!! I used to do it all the time and when I start doing it now I look back on my track record when I would project doom and gloom and most of the time I was wrong.
Do not get me wrong, you need to try and be prepared for things not turning out right, but there is no reason to dwell on it, it leads to nothing.
