To obey is better than sacrifice. Learn to forgive others. Yes, it’s painful when people hurt you, even when they say things you don’t like. Don’t be bitter. Talk with person and express the way you feel about he/she might have said. After doing that, you will have free heart and you will not go to sleep with bitterness and anger. Being bitter and angry is not good for your heart.

Ephesians 4:32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.
