I don't know what lies ahead in terms of my job

I am on an extended probation -- 8 months instead of 6 -- and I have to write an essay? a paper? due on Monday, March 16 on whether or not I have passed the probation, and have I done enough. It doesn't sound like it can be summed up in a few sentences. Plus we are going to meet two days later, when I will get my final probationary evaluation; and it will be revealed if, as my supervisor put it, "we will continue our relationship here". Everyone says that the super likes to fuck with people quite often. I don't take to this too well. I fear that I will lose my position, and that would leave me in a place similar to limbo or at someone else's mercy. I know that God has led me out here, so I have to trust that what has been going on is working towards some other good. I guess we'll see...
