I agree with Dorothy! You were feeling good about yourself!!! That's, like, 90% of the battle right there! Seriously, the way we see ourselves is totally dictated by how we feel about ourselves. And that, in turn, changes how others see us as well. You've lost, what, 32 pounds? Holy smokes girl! you should feel good about that! Who cares what you see in a camera picture or whether or not anyone's commented? You are on the right path and doing great. Focus on that.
Of course, it's easy for me to talk. Everyone in my family has noticed, most of them with little or no encouragement from anyone else to look. I get why it bums you out though, because it really is a sense of validation when people notice. You are doing this at least partly for appearance, and you'll never know that you're succeeding if no one says anything.
They will though. Be patient. Some people just don't "see" weight very well. And some people do wait to say something until they are 100% positive, just in case they're wrong. But it will happen, don't let this discourage you.
