Oh my, what is a mother to do?

Just found out that Steve's grandmother fell again and it may be that my sitter is going to move to where she lives to take care of her...what am I going to do?? I have been praying that God would show me if this nursing school path is the one that He would have me on...and I am trying to let go and let Him take control but now I am really scared that His answer is No. Trying to remain calm...
