hey man/ girl... my friend had the exact situation. My friend's reason for terminated sevis was that he never went to see his international adviser.
But then my friend went to talk with the president of the university.  And everything was taken care of. 
So first go and talk to the president. 
i dont know what your reason for terminated sevis is but whenu go see the preisdent make sure you make a good excuse if u had stopped going to school.
