need help

I have 3 kids and was able to pay our rent this month but I don't know about next month. I rent from my Uncle and you would think since he is family, he would want to help but all he cares about is his money. I was laid off 3 years ago and went back to school. Graduated with my Associates degree (during which I lost all 3 of my grandparents and gave birth to a baby girl). I have stayed at home since graduating because my husband had a great job and I didn't want to take something away from someone who really needed it but my husband's hours got cut and now he barely works 35 hrs a week. We took in someone to live with us (a friend of my brother's) hoping that would give us a little extra money but all she did was eat our food, run up our cable pay-per-view (which they cut off because of this), run up our power bill and she never once paid rent. We kept asking her where her money was but she never paid us. Now, we not only are as in debt as we were before, we have no cable and can't pay the 300 bill to get it back on either! My mom let us borrow a converter box so that we could at least have SOME tv. My parents promised to help us when they got my grandparents estate settled but my uncle (the one who owns our house) pitched a fit and contested it during probate because I wasn't a "child... only a grandchild and I don't deserve anything". So, I just don't know what we are going to do and I have been praying but it just doesn't seem to go anywhere and I just think about giving up.
