Broke student, need money to buy books and food.

I only have $5 in my bank account and $2 in my wallet. And I am a full time undergraduate student who's in a financial crisis. My single mother is facing some financial difficulties and I don't want to ask for money to her because I will be a burden.
I'm seeking for job in my area but it's difficult since I'm a full time student. (And in my country, it's hard for a student to get a job) I do some freelance job, but it only covers to buy some books.
So I really hope someone out there will give me some donation. I accept any amount of money, even if it's only $1. 
I don't know what to eat for now and maybe for a couple next month and how I will buy required text book. 
I really need your kindness to help me :(
