What does that mean?

When I lost my hair to alopecia at nine years old, I was devastated because I was different from everyone. After months of hiding my hair loss, I looked at myself in the mirror and stared at my new look. Nothing was going to change, and I had to accept it. It took me years to accept my new appearance, but I soon saw my condition as a challenge. Now, I am using my story to encourage others to see that God can use anyone to make Him known.
