I think sometimes people will smile more broadly rather than say something. I mean not everyone is comfortable giving a compliment either. Some people may want to say something but they may not know how to. Have you considered that?
On the other hand, I hope that you aren't waiting around for others to notice as one of your incentives to lose the weight. I'm not saying that it isn't nice but if you never get a compliment would you stop trying to do something this good for yourself?
I have read that if you aren't losing it for yourself you increase the chances of regaining that weight. I am sorry to hear that your family didn't notice but maybe there is still some part of you that you feel unaccepted by them and you feel that if you lose weight they will love and accept you more. I doubt that. Our families love us as we are. We just usually don't give them enough credit for that. The same with close friends. My DH loves me already. He has said if this will make me happy then he will support me in it but he doesn't wag a finger at me if I have a dessert or order pizza.
After all, people come and go in our lives and if we hung all of our needs for stroking on every one that came along we would be very insecure and less confident than if we do it for ourselves alone.
I would suggest that you try to build your confidence based on how you feel you are doing. After all, other people's opinions are just that---their opinions.
I noticed I was losing weight when my pants started to droop (my pot belly wasn't holding them up) and I almost tripped over my pants legs. I have also taken pictures of my weight lose journey so I can see for myself what I look like. (see my photo blog on this website "....pixstosee). Maybe, doing something like this will help you realize that "Hey, I am doing this..." and help boost your sagging ego.
Don't worry you're doing great! We are proud of you!
