Yes, absolutely. It is so hard not to do this especially if you have heard a lot of negativity from other people during your life.
I find that when I'm looking for progress, it's much easier if I wear the same outfit from the beginning and look for good changes. If I just stood in front of the mirror every day examining myself, I would always walk away feeling bad. We always manage to find the bad things and focus on them.
Even after losing 50 lbs, I can hardly tell. But then I have to remind myself that when I slowly gained from 300 to nearly 400 lbs, I didn't really notice that either. It might take a while before I can see the changes on an average day. But when I put on the outfit I tried on at 396 lbs and then again at 346 lbs, I can see the changes. The skirt is looser and the shirt fits better. So, I focus on that.
It's hard to stop being so hard on yourself! But I do think it's possible.
