God is helping you to recognize your gifts again in the singing, so He will with your other gifts as you re-acquaint yourself with your talents. Moving forward with your journey with Him will give you the joy and peace that you are looking for. Looking back can't do that. Your authentic self results in doing from your gifts and not from the lies that you have somehow let yourself believe. As was said before the Holy Spirit will lead you into all these things. Trust that God loves you and will never forsake you and that's what really matters. Let the peace of Christ rule your heart.
