The devil is very much real, and he is the enemy of every Christian. His agenda is to destroy you -physically, emotionally, and spiritually. But it is also important for you to know that God is very much real, and He desires for you to be healed– physically, emotionally, and spiritually.
Spend some time thinking about the areas of your life that the devil has been tearing down, and pray over them. Your Heavenly Father always hears you, and He will give you direction.
