I do not profess to be a financial expert
But, dependent on how happy you are to explain the intracacies of your financial problems with your mother, you could talk to her about where this money would be most useful in some detail and then how quickly you could get it back to her. If you show diligence and a serious attitude towards the problem, as well as illustrating that she's not throwing her money away, she may agree to loan you even more if it would make a difference.

Failing that, kidneys are worth a lot these days.
