Hi LY,
I totally understand you and I have to say that I am supper anxious about your papers (I have to wait 4 months more to get mines). Now, talking about "how to keep ourselves busy". I am doing a volunteer every morning. It is not the nicest job, but for me it is a good way to learn English, to meet new people and get "canadian work experience". Another thing that I have been doing a lot is reading. I can recommend you some really good books: "The tipping point"; "Outliers"; "Plan B 4.0": etc... It is really bad to be in a situation like the one we are in. But we have to find the way to seize this incredible amount of free time.
LY, you are incredible close to get you paper... I should spend this last few days making a list of what you want to do once you have your papers and how you are going to do it.
Cheers
Pepe
