living REAL simple (help I need a life saver)

When going over finances again i realized that there is not a whole lot of room for anything. I am just talking about basic necessites, clothes for the kids, haircut for my son before school starts. My downfall is that we rent furniture, nothing extravagant. the table we eat on, the beds that three of us sleep on a washer and dryer. we cannotget finanaced and we cannot do without until we save up for it, which would never happen so we rent. I helped a little bit with that last week when they came and got my bed, now I am sleeping on my daughters bed with her in the kids room. I have sold almost all of my clothes, my lamp, my jewelry box, some of the kids toys, some of their clothes, our books for the most part, some of our vhs tapes. Next weekend i am going back to the flea market to try and sell everything else that hasn't been sold yet. I am trying to get out of debt, I just buy what is needed not wanted, I am not buying school clothes this year, I only bought what I thought they would need on the school supply list. I had to write a check last friday so we could eat, now i am in the red at the bank, this week every bit of money I get isgoing to a loan I had to get last month to buy food ( we are feeding seven) and pay some bills. I know that i am lucky because i still have a roof over my head and i have a job interview today. I just think it is ironic that by trying to spend less and live as simple as i can i am getting even more in debt, now it is to the point that I can't provide basic neccestites for my children. I have tried to use local charities for them and they give me the third degree and assume that because Ilive with my mom (who financially is in the same boat) that I should not need help. giving up my bed has helped we are saving a 140 a month now. i just do not see it because i never had it to begin with.
