The anticipation can definitely take a toll on you, but let me just give a glimpse of my path towards PPR.
I came to Canada as a student in 2011 and studied for 4 years, started working in Canada mid 2014 when I heard the rule for PR had changed. I took a deep breath and told myself that things will work out eventually, besides I had 2.5 years work permit/visa left. As time passed by I got married and applied for my wife's visa (Spousal accompanying visa on the basis of my work permit) . They make you go through a questionnaire and then ask you to submit certain documents and I did that. Turns out they never asked for my work letter and I did not submitted it. Her visa was declined. Applied again with the work information, declined again because they think we will not return to our country when our visa expires!
We didn't give up, we applied for her visa after a year as a student this time. Again rejected for the 3rd time! After that my work permit expired and I had to apply for a student visa in order to stay back. We eventually got an invite under the express entry this March and Applied in May and lo and behold we both got approved yesterday.
My intention to share this roller-coaster of a story is simple, don't lose hope! I have been in the worst of the worst situations with missing out on initial years of my marriage to being pressured to make decision whether to stay or go back home and boy oh boy going through depression and anxiety! It was really difficult.
But, things will work out, they might take longer but eventually they will. Just be a little more patient. If a case like mine can be approved, I bet yours will be too. Good luck and thank you for the emotional support all along the process.
