Dealing with my mother\'s death

My mother died early Monday morning 3/3/08.  I was in denial at first and now I am trying to deal with the realization that she is gone for good.  I lived with her for many years and it was just the two of us, I am trying to find a way to get through this.  The nursing facility she died at told me I couldn't stay there, it wasn't a hotel, after I spent the night there because I couldn't go home alone to an empty apartment.  I would appreciate any help.
