Remember that above all, life is short. Everything is temporary. The wait makes it feel eternal. I know that because I am in the same boat as you. Nothing in life is worth worrying over especially if affects your health (BP). Do you want to live longer or die sooner? Canada is just a country. At the end of the day, it's up you to make yourself happy. Everything else shouldn't matter after that. You can find yourself in the worst place on earth yet live such a fulfilling life that makes everyone in Canada jealous. This is not to undermine Canada as a country. In fact, this should only serve as a reminder to put things in perspective for all of us. We all want to make Canada a home where we realize our hopes and dreams.
Nothing in life is worth stressing over. It's very hard not worry. I myself am as guilty as everyone else. Try to relax, spend some quality time with your wife. Time flies by when you are having a good time.
The past is the past, the present is what you choose it to be and the future is unknown.
The actual work starts once you arrive in Canada. This whole process is just a ticket. Eventually, Canada is what you make it to be.
By the end of the 6 months mark, call IRCC and ask them for more information. They strive to complete applications within that time scale and they should be able to provide with you an explanation.
If this was up to me, you will get your PPR right now.
