I don't know why I think my jeans won't fit when I put them on, even though they fit a couple weeks ago.
I don't know why I thought all those extra-large tankini tops would fit me when I brought them in the dressing room when I just got rid of a bunch of swimsuits in that size.
It doesn't work that way anymore.
But my brain still works that way, and it's going to take time to remold it to my new normal. That's the cool thing about brains -- you can rewire them but it takes time.
It's not really body dysmorphia because I DO see the changes when I look in the mirror. It's more like my brain having to play catch-up with my body. When I'm folding laundry I'll hold up a pair of my jeans and think "How do these possibly fit me???"
But they do.
