i get what you mean about not really feeling/seeing it. i feel the same way.
but i do have to say you look FABULOUS. you look like you've lost more than 40lbs. you go girl!
You can DEFINITELY see the difference!! Way to go! I am the same way mentally though... I've lost over 120 pounds total, and 60 pounds this run, yet I don't see a difference in the mirror either. Go figure...
