Too Much,
One of the things about acceptance, especially with an illness is the recognition that recovery is just that.... recovery. You've recovered from the illness but it doesn't make you immune like you would be with a vaccination against a disease.
My MO (medical oncologist) told me I'll always be a survivor. I'm "cancer free" but still a survivor. I'm healing as are you, but as a survivor we're reminded of the battle we've been through.
Just like I have my reminders, so do you in the form of a blip now and again. Eventually, as we recover more and more, the reminders become less and less. As I'm sure I'll feel better a year from now, so will you. Keep in mind it wasn't that long ago you were grappling on all fours with the Dragon. Give yourself some slack. I know it's tiring and frustrating but at least this time you're standing on two feet wielding a sword..
