What does "Hurt" do to you?

When you're hurt by someone what do you do? Do you allow it to make you bitter.... or better? Remember it's your choice on the direction you move. “Forget the former things; do not dwell on the past. See, I am doing a new thing! Now it springs up; do you not perceive it? I am making a way in the desert and streams in the wasteland.” Isaiah 43:18-19
