<human>: Can you give me a shortened version of the text?

I was slowly building my savings until two major events, my mother's stroke and my sister's death, along with the start of school drained me of everything. I currently have $40 in my checking account, though thankfully no debt.

My income now is around $1,500 a month. However, I am also my niece and nephew's next of kin; there is the possibility in the next 5 years that I end up being their legal guardian. Additionally, since my mother only just got back to work, I also have to contribute to rent. My expenses are at $500 a month, but will rise to about $1,000 a month starting January 2017.
<bot>: How do I save up enough to have an emergency fund, care for two future children and pay for school while still in school?
