Medical Career in Germany

Hello!!!  I'm a 3rd year medical student from the Philippines (only need one more year to graduate--that is--internship and post graduate internship right after), but due to certain circumtances, I have to move to Germany, which requires me to stop my studies, however, I would very much like to continue studying...  I've been informed it's quite possible.  I would very much like to hear from someone who's gone through the same situation as mine...  or heard of something similar.

As of the moment, my German is deplorable.  I've read up about German Grammar--complicated what with the 4 cases, all of which don't exist in the English language--but I thought familiarizing myself with as much as I can will help when I do take up formal German classes.  Yes, I do intend to learn German.  So what else is necessary for me to be able to continue studying there?

Will anyone help me, please?
