You went throught the tunnel and now you are a better professional! :thumbsup:

Apart from the other valuable advices that you have received, be sure of being calm down when deciding what to do. Everybody has days when a project seems more than we can manage and the future looks darker that it is in fact. You seem to be having one of that days So, that days it is better to walf for a walk or something similar, and free your mind. Next day sit in from of the project specificactions, cut them down to achievable parts and create a realistic schedule. Remember, sometimes things look better with the light of a new day :)
