You must break free of demonic bondage and satan's prison. I am one who is going through exactly what your going through. It is best to find out what type of demon your dealing with. I pray it is not a King or Queen demon, these will not go away with just a few prayers., They cast spells and are very dangerous. You would have to cover self with blood of jesus, engage in fasting, praying, spiritual warfare and church for hours for relief. If you can't sleep at night as i get demon attacks as well, it is probably a familiar spiriit or evil monitoring spirits. You evil monitoring spirits preying on her be cast down! I command you to leave her in Jesus name. There are also "Princes of terror", dukes, nobles, demon captains, generals, fallen angels, etc. Say Lord Jesus Help Me, it'll back them off of you. They will return, demons don't back down and good luck talking to anyone worldly such as a psychiatrist about it. They'll be quick to claim it's some form of chemical imbalance so they can write you a prescription because they don't really care or love us like Jesus does. I say to any therapists who doubt the truth of the matter, Are you sure it a "chemical" problem? Do they even know that for sure? You understand that they're just GUESSING, right? Because they want it to be ANYTHING other than DEMONS!! Can't be that! Then we would need JESUS!!
