Adespota. I read your story and things may be different in Canada. I will tell you what I had to go through to get Social Security here in the US. I applied for disability with some medical information and got turned down. I applied again with more medical information about some mental health issues and got turned down. This is normal here. The gov't knows that a lot of people try to get social security for false reasons. I then had to hire an attorney who specializes in social security cases and had to sit before an administrative judge and testify in person. My attorney made sure that I had documentation from all of my doctors and it was during this third proceeding that the judge made my case fully favorable. Things may be different where you live but what helped me was a lot of documentation from professionals and the attorney.
Hope this helps. Best wishes.
