Trying to see what I don't see

Everyone has been repeatedly telling me they can really tell, especially in my face, that I've lost weight. I just don't really see what they see. Last night I found a picture from August and compared it to a picture taken about a week ago. I can see a
huge... No pun intended... Difference.
I'm wearing different clothes that I couldn't before and also clothes that were tight, but I refused to go up a size.... Fit way too loose now.
