You've worked hard, (even if things did not go exactly the way that you planned) now you've made some progress. People can see it, and will comment. Don't shrug it off. Accept the compliments, and validate yourself. You've worked hard to get here- so enjoy it.
Progress is spotty- some garments will fit for a long time and through lots of weight loss. Other things will begin to fit in fits and starts. Sizing is so erratic, and there are lots of different ranges, so don't let that frustrate you. It will take a while for your mind to catch up to your body sometimes. Be aware, and be diligent on fit. If a new size fits, it's not because it runs big- it's because that fits you now. Try to wrap your head around it and enjoy it.
You have the power to change your body- don't give that power away!
