You can have peace, perfect peace. Just keep your mind stayed on God. He will give it to you.
Trust Him and see, and be blessed.
Isaiah 26:3 (KJV) – thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee.
Psalm 34:8 (KJV) – O taste and see that the Lord is good: blessed is the man that trusteth in him.
