When you feel like you’re not yourself because of something that keeps bothering, oppressing, or weighing you down (like not trusting people, compulsively making lists, or over-/under-eating), then that’s a good indication that you’re under spiritual oppression from an evil spirit. 

The way to get victory is 1) fast, 2) meditate on key scriptures, 3) get prayed for. 

So if you fast (a meal, favorite food, etc.) and continue to think on a handful of key scriptures for about 3 weeks (memorizing them, loving them, savoring them), then have a leader in your church pray for you to bind and cast out the oppressing or afflicting spirit.  After the prayer, you’ll experience some freedom. It could be complete and immediate or gradual. Either way, there’s hope!
