TEacher...I have a question

Today's language lesson was really hard!  We have started grammar and I barely know grammar in English!  It's a lot to learn in three months and sometimes I leave class and my head is just spinning.  Albanian used cases which are really difficult and the word structure is much different.  For example, there is not word for "the" in Shqip, so we change the form of the word to make it definite.  A friend is Shok and the friend is Shoku...and that's just the singular form of the word.  Yikes...I should probably go study!
