The sooner you apologize the easier it is. Be specific with your apology. Don't qualify your apology. It's an indictment of the person you've injured. Learn to like your body.
Every body does amazing things.
You may find it hard to accept parts of your body. This is the result of someone else's judgment about bodies. You've heard derogatory things about your body or bodies similar to yours. You accepted them as true, usually when you were a child without the ability to understand that another person's judgment does not constitute the truth. Identify parts of your body you like.
