So I think I've gotten rid of it.

I continued with my plan and later that night. When I started having those feelings of fear, I told it to leave. Nothing physical happened that I could see, which may be a good thing. The closest thing to a 'sign' I saw was that a breeze started blowing through the open window. Then I started praying for a while for the place to be purged of the evil and filled with the Holy Spirit so there would be no room for the evil. It may sound ridiculous to certain people, but after that, I definitely felt better. I was even able to sleep in the room which I had been unable to do for over three years. I've even set up my stuff in here and haven't had to leave.

Another interesting thing that happened was that I turned on my new wireless headphones earlier to watch a video. The headphones double as a radio, so sometimes they pick up radio signals even when set to audio input. And you know what was playing? The Christian station. What are the chances of that happening. Of all the stations interfering, it was that one came out the clearest. You Atheists can leave it up to coincidence, but I'm sticking to my faith.

Of course I don't know for sure if it's gone or not, but I do know that holding suspicion and worry can invite it back in, so I'm going to do something notoriously hard for me to do: Be optimistic. I'm not going to pay attention to the fact that I didn't see signs of it leaving, I'm going to pay attention to the signs that it's gone.

Either way, I'll keep you guys posted.
