Try going for a walk someplace nice...and remember that you are loved.  I love you.  Plenty of people love you.  Everyone loves you, most of them just don't know it yet.  Don't let humans judging you get you down.  It's in our nature.  So is you letting them get to you and putting yourself down.  But, you can do something about this.  You are beautiful.  Keep your head up.  Be nice to others and yourself.  Love will save you.
