I have custody of my younger sister and we are currently renting a house and i lost my job Nov. 4th. I have used up all my savings to pay rent for two months and all the bills but i\'m 400 dollars short of making rent this month and i have already gotten a three day notice. I dont know what to do. i am making myself sick worried about all this..please some one help me. I have been going to interviews and no one wants to hire anyone until the first of the year. i will pay back the money as soon as i can. I am so heartbroken i\'m doing this to my little sister. i dotn want her to remember this. She is so worried we wont have a place to live and i am too. Please someone help me...anything that you can help i would appericate it. We cant afford to do christmas this year...my sister says she understands but it breaks my heart that there is not anything i can do for her....i feel like the worst sister ever.
