Trust Issues With Ownself

Hey guys,
According to Pete, the day before yesterday, I was basically wavering between human and proxy, and it took just one one-on-one encounter with Slender Man to render me unconscious for over 24 hours and finally sent back to Dec. '10, again. That means stick must have a hole bored into my head that it's able to get into to mess with me. I'm sane again on It's whims.
Does this mean I'm a liability just waiting to be taken over again? Will I be able to maintain control when It inevitably comes back and we have to content with it? Will I attack my new allies? I wish I could be confident with myself, but I can't. I want to help out, but I don't know if I can.

I'm going to have to give this a lot of thought.
