30 pounds is amazing. You should be very proud, and I'm sure you've gotten lots of compliments on how great you're looking. The thing is, it's really hard for you to notice your own improvements, since you see yourself the most!

I also know I tend to see myself through negatively-tinted glasses. These photos will help you notice the difference; without your mind making you focus on what you might not like, you'll be forced to notice what you love.
