Will I ever care again?

When you lose everything you cherish there isn't anything left to care about.  I'm left empty, emotionless and alone.  I grieve for the return of life as I knew it a year ago.  Instead I sit here.  I have forgetful friends.  Two of them made plans to spend time with me this week and weekend and I think both of them forgot.  I don't have the energy to remind them either....will it ever feel better?
