Matt. You're dealing with spiritual oppression.
Oppression is much different than possession, however both deal with attacks from the enemy.
Ephesians 6:12 "For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
Here's my advice.
Go to the Man of God in your life, ask him to anoint you with oil and pray for you.
You need to break the back of that spirit that is oppressing you.
Fasting would be beneficial as well.
