Where do you live? Its a matter of finding stable, God-fearing people near you who actually understand spiritual warfare. They can help you if you also will do your part. Draw near to God, read the Bible a lot and ask God to show you any disobedience that could have given the enemy grounds to attack you. Then repent of it. Believe the promises of God in the Bible, given for your good. Especially read the Psalms. They are good for spiritual warfare.
