I wonder what I need to do

I wonder what I need to do in this situation. I am studying to get licensed as a secondary science teacher. In order to do so, you need 3 student teaching experiences...I have one done, which is my observing of the actual school teacher. Last year, I did my half-day student teaching but I seriously ill and could not finish or go on to the next level. Ok..fast forward to this school year. During the month of August, my coordinator wanted me to develop a teachable unit before I can go back into the classroom and turn it into him. That is completed but I have been waiting since September for a placement. I had one 2 weeks ago but it fell through. I talked with my supervisor and he thought that he had another one in place for me. But I have not heard in the last week. I went in to talk to him last week...he said there is nothing for me this term. I told him that my time is almost up for this term. Any suggestions for me??
