You will be there and know that somehow she'll always be with you no matter what happens. A mother's love for her daughter extends beyond the distances, I'm sure you can feel it too. It's obvious how close you two are; she has raised you in a beautiful way and taught you how to be strong too. If you need to be the woman of the house, your best will be enough.

Talk to your school about what is going on, they'll get it. It's tough how when times were good we thought we have all the time in the world... and then we realize that time is our most precious resource and constant running out... but it's all perspective. Make the most of the time you have and try to always love like there is no next month, next week or even tomorrow.
