Below are some bible verses that have helped me.

Romans 8:28 And we know that in all things God works for the good of those who love him, who have been called according to his purpose.

John 10:10 I came that they may have life, and may have it abundantly.

Romans 8:31b If God is for us who can be against us.

Nehemiah 8:10b Do not grieve, for the joy of the LORD is your strength.

Psalm 23 The LORD is my shepherd, I shall want. He makes me lie down in green pastures, he leads me beside quiet waters, he restores my soul. He guides me in paths of righteousness for his name's sake. Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me; your rod and your staff, they comfort me. You prepare a table before me in the presence of my enemies. You anoint my head with oil; my cup overflows.  Surely goodness and love will follow me all the days of my life, and I will dwell in the house of the LORD for ever.
