"The only few things i thought was possibly when i was working at the assisted living place that i tried casting spirits out of people or the elderly who had dementia..."
Ah, I remember some years ago as a youngin in the Lord, a group of us guys took it upon ourselves to cast out a devil in a man that was troubled. I thought nothing of it until the Pastor later asked me if we had done something like this because one of the guys that were there was being demonically attacked and that we should have consulted persons that knew about casting out devils before attempting to cast out devils ourselves. I heard nothing more about the situation or what happened to the brother.
One thing I do know about casting out devils is that just because it says that we can cast out devils in the bible doesn't mean that we have the right to. We must be led by the Holy Ghost to do these things.
Some of us get antsy because we want to live out the bible and we can't. We can't do it without the Spirit of God leading our every step. Plus, we need to be granted authority. Just because we have received the holy Spirit doesn't mean we have the authority to do what we want. We must be given authority to cast out devils and not everyone casts out devils.
It sounds like you've opened a door for these things to harass you. The scripture is clear brother,
1) Submit yourself unto God.
This means that you submit to His ways of doing things. You stop what you are doing, repent, asking God to forgive you for entering places that you had no business entering and
2)Resist the Devil.
This means that whatever hell has been sent to you that you stand your ground and stand you must calling upon the Lord for help. You can get everyone in the world to pray for you, but it still takes your Will to resist the devil and not give into the fear. Yes it's hard, it's hard to resist. Look at our Lord in the wilderness resisting the temptation of being able to turn a stone into a loaf of bread to eat, the bible says that He was very hungry. He could have done it, but than He would be no different than Esau who sold his birthright for a piece of nothing.
What we will pray for is the strength for you to stand, to resist the devil.
3)And he will flee!
The promise is that he can't stand it when someone is faithful to God and not to him. Satan is used to having people bend to his will, but then there is this "little flock" that just irritates him to no end. Satan comes with all his darkness and overwhelms the believer with temptation, as the resisting begins the darkness increases the temptation becomes almost unbearable and then like a flash of lightening, darkness flees because it can't comprehend it. It can't stay. It flees away until another set of circumstances bring it back to see if we learned anything from the last temptation.
As for your affliction,
"Many are the affliction of the righteous, but the Lord shall deliver us from them all."
I do recommend that you see a Doctor about your condition. It could be something serious it could be something that is not demon related. And whatever you do don't mention about demons attacking you, or he'll send you to a psychiatrist.
And then go and see one of the pentecostal variety ministries and find out which one of them deal in casting out devils and find out from them if your story fits in with any of their experiences they may have a word for you.
Good Hunting!
