I had my surgery a week before you (Nov. 30) and you could be my twin. Reader, knitter, etc., all of it. Same stuff going on. Never ever in my life depressed, but I was, in spades, the first 3 weeks post surgery. I still don't know why because like you, I had a reasonably good outcome and having gone through my son's Grade IV brain cancer journey in 2009 with no depression, this was totally unexpected. Thank God the awful headaches I had for 2 weeks are gone or I would still be depressed!
But tonight I'm sitting in a hotel in Rolla, MO on our way to Oklahoma City for a quilt show (we vend). So I'm back to work and functioning fairly well...even driving through the snow storm (which in this part of the country, they do NOT know how to handle). Of course, I had to see the eye doc this morning because it turns out I have a scratched cornea (from the continual eye dryness, post surgery), but with my green eyes, the red infected part makes my eye look very Christmasy (albeit 2 weeks too late)! So now I can laugh about these little setbacks. You will too. I'm even used to the really loud tinnitus now--like an old friend--the new normal.
So, 6 weeks post-surgery, you'll be better and happier. Get a Kindle--you can change the font. I recommend the Hunger Games trilogy by Suzanne Collins. Kind of science fiction in the Lord of the Flies vein...very mind distracting...just the thing to take your mind off "you." Be well...life goes on.
