I couldn't understand your situation more as I am in exactly the same situation. I have currently living in a self-imposed isolation and have been avoiding talking with relatives, friends, ex-colleagues about this matter, and the reason I act this way is the same as yours. There is basically no timeline for SS as it is done by CBSA and CSIS and therefore out of the control of IRCC. Because of the lack of agreements on the maximum time for SS between IRCC and CBSA, the SS can take an unreasonably long time. If you search online, you will find lots of petitions about this, and people have experienced suicide tendency, depression and even more serious issues. I can't help checking my email and CIC account every 2 hours during the day with the hope that there may be an update. Although I'm an inland applicant, all my future academic and professional plans are still depending on the result of this PR application. With this application pending, I cannot move on at all. I am mentally tortured by this on a daily basis, but there is absolutely nothing I can do about it. The lack of control and the great amount of uncertainty in this process is really killing everyone. I have already called IRCC numerous times and have ordered IRCC,CBSA,CSIS notes, but none of those notes have arrived. I just feel that I'm the least lucky person on this planet, but when I come to this forum, I see hundreds of people facing the same situation, and no one knows what to do..
