psychological or residuals?

Maybe it is all in my head as i have had the big 1 year mark in the back of my mind, but last few days I have felt worse than i have in a long time. For the last couple of days my arms and legs have felt really heavy and i havent felt quite right. I am hoping it is just residuals and not the other “R” word. Surely if i was going to have a relapse the odds of it happening exactly a year later would be pretty slim.
