I just typed out a page of info about my depression and have come to a conclusion that my depression stems from the fact that the illness I had at age 12 compromised my education. My grades should have been 20 - 30% higher for all the effort I put in, and it was never enough. I struggled, blood sweat and literal tears, no one helped me, instead help was actually refused. I felt rejected, isolated, worthless back then. A comment on my gr11 phys-ed report from the teacher, this was now 4 years after being sick said I was the ONLY student of his that lacked stamina, needed frequent rests, and underperformed to my age level- at the time I laughed at it, but it was true. He said I needed to see a doctor. He recognized a problem, one that I was not allowed to talk about.
Today, I feel the same sense of helplessness as I did so many years ago, as I struggle to make a living in my career. If I had not been so sick, my career choices would have been different. Life is so friggin cruel and I do not know where to turn.
