Endings

I have come back from my holiday  to such sad news  - the dear lady who I have taken care of for 16 months has taken a bad turn and has been given weeks to live. 

 She is  in a Nursing home  and I spend 4 to 5 hours with her ever day.  

This is so sad and I am feeling a bit lost!   

I am not supposed to get emotionally attached, but how can I do this job without caring? 

She is such a sweetie, not a bad bone in her body and I have grown so close to her........
