You would really not want a negative friend who keeps mentioning to you about your acne, your scars, your weight, your complexion, or anything of that sort , the moment they see you right?
Then why do YOU do keep mentioning them again and again inside your head the moment you look at the mirror?
Stop being a toxic and negative friend to your body. It's the most selfess friend you could ever have. Apologize to it and work on it because you Love it not because you Hate it.
