I feel like throwing in the towel every update. It is a ritual for me. But things work out. I had one site that was strangely banned from Google for a year (it now appears eventhough nothing has changed); however, during that year I found places to get links and real ways to generate traffic to the site. Despite not being on Google it still made money. The main thing is not to reliant on Google. It may be the biggest potential source of traffic, but it is not the only way to get visitors.
Good luck! Get another towel. :)
