how old is your little niece?

if she is old enough to Instant Message, maybe you could stay in touch with her that way?? Just a thought.

you have such a caring heart
It is very hard when we feel torn between work and the desire to give more of ourselves to those who need us...I know the feeling all too well

I hope there is a way you will be able to reach a balance in being there for her and still taking care of your responsibilities to yourself and your studies
