feeling so helpless!!!

My youngest sister just skyped me..asking me whether she can take more painkillers for her toothache. She had surgery about a week ago to take out two wisdom teeth and now the stitches are painful and her gums are not in good condition and she can't sleep. She has an exam tomorrow and it is already 2 am in the morning. Here I am thousand and thousand miles away and skyping with her and wishing that I am there to take care of her. asked her to take panadol but there was no more panadol at home. I feel so helpless that I can't do anything about it. I don't really know how she feels but I just hope that she is okay. After our mom passed away and I left, she is staying with my brother. He is going a good job taking care of her, I know that but I just wish I can be there. She is alone, no dad, no mom and she looks so helpless. I know she might be much much stronger than I think she is and even much stronger than me. But as for know, I just want to be there for her. Ya Allah, please protect my baby sister. Please give her the strength. Amin.
