"I’m so afraid that I haven’t changed.
What if I haven’t changed? What if I haven’t learned ANYTHING???"

Hi BarbiGirl - don't let these statements worry you. If you haven't changed and make a mistake again - you just keep going. Sometimes we need to fall and make mistakes until we learn. Believing in these statements will just hold you back. Forget about the 'what if's'. Best of luck and believe in yourself - it doesn't need to be perfect.
