One of the things I learned during my whole weight loss process is that it's a giant mental game. The physical part is easy—exercising and eating right are simple enough—but our mind is our worst enemy when it comes to this stuff.
I too wasn't very critical of my body until I started losing weight. I remember thinking "ok, if I could lose 40lbs then I would be happy." Well I lose 40lbs and I still wasn't happy. I got to 140lbs and I STILL wasn't happy. I'm still not even completely happy now because there's such a huge disconnect between my actual body and how I see myself sometimes that there are times where I just can't process what I look like right now. I still feel like my "old" self but I must admit that with each passing day I'm getting better at feeling like the "new" me.
Others might have noticed your loss but not said anything at this stage of the game. It wasn't until recently that some people finally mentioned my losses and even then they didn't say anything about weight loss, just that I "look fantastic." Some people just don't know what to say...my supervisor first interviewed me just after I started my weight loss journey last year and when I saw him recently he said nothing! He—and others—sometimes just don't know what to say.
The best tool on this journey was the ability for me to take pictures and hanging on to some old clothes. You don't see the difference sometimes until the pictures are in front of you or until you try something on that was once too tight to find that it fits or is loose. I threw on some clothes recently that were once tight and they literally fell off me. It was shocking.
So relax, take pictures, try on clothes. Hopefully you will feel better...and even if nobody ever says anything to you, YOU will start seeing your progress
