You are so amazing! You are true inspiration!
First, get rid of that dirty old lying mirror you have. Just stop looking at it. Do you happen to have any old and current photos? If so, compare the two. You will be amazed at the differences you will see, such as how much of you is missing and how your face is angular instead of round, and all that wonderful little stuff. Once you see that, the mirror will hide its head in shame and you will start to see your beautiful self as everyone else does.
Then, get some clothes that fit. You are hiding behind clothes that are too big. When too big, they appear frumpy, and frumpy tends to make us feel gross. When you are in clothes that fit, your confidence will radiate and you will look in the mirror who is still ashamed he was showing you a false image and you will see just how truly beautiful you are.
And you have come 200 pounds. You have learned healthy eating habits. You have busted your arse to get here. You won't go back. You know how hard you fought for this. You know, deep down, you will NOT give it up without a fight for your life.
Have faith. You are amazing. You are awesome. You are inspiration. And I so want to read your story now...where ever could I find it? (HINT, HINT!)
