You be careful, OK?
This is important to you I can tell, but don't go hurting yourself trying to prove yourself.
You are a strong and capable young man. You are kind hearted, generous and worthy of respect. You have nothing to prove, and no need to prove yourself to anyone.
We love you the shape and size you are.
Not to say we would not love you WHATEVER size and shape you were!!! But getting squished into a different shape might probably hurt a LOT.
