Everyone, all who got their visas and others who are still waiting, goes through that stage. Even I went through that stage. But during the times that I'm not hearing any news from CIC, I taught myself to be calm and patient. If you have tracked your application kit, there should be a signature of the person who received your kit and you can view it online. If you are sure that you had everything filled out, all necessary documents are there, then do not worry too much. CIC gets tons of applications everyday and believe it or not, they go through each file like read the cards, look at the pictures, read all the documents you filled out. They go through every page/material you sent. It is true that sometimes unnecessary things happen but on a rare occasion. And if in case that happens, the CIC make amendments by putting your application in priority. I think I've read the situation of one member here who was waiting for approval but took a while to get it (the one you mentioned). His file wasn't misplaced. He forgot to sign some parts of the forms and he just assumed it was misplaced because the call center agents didn't give him a definite answer about his application. His application was returned to him and after reviewing his kit, he sent it back.
If first stage is stressful for you, then wait til you get to the second stage when your files are sent to CEM. It's even more stressful because some people get their visas in two weeks, some in two months. When your files get to CEM, the date your application was filed doesn't matter. Some who even filed later than you might get their visas before you get yours. So just relax. And breathe. You will eventually get what you want. You will eventually be with your spouse.
