morning jen,
dont feel powerless hon, just do what you feel you can, and just remember sometimes its as good to just listen than to do any physical stuff...try not to stress too much, it may be as upsetting for your friend to see you upset, than her illness stressing her...Did that come out right,,hope so, but if not I hope you know what i am trying to say..

anyways let her know please that she will be in my prayers and as always you too sweetheart!
