I do, and it is tough. Sometimes (often, to tell you the truth), I don't have the things that I need personally. My kids don't suffer, but I do. Sometimes my kids need something that I can hold off the purchase of because they are okay, but will need it soon. I try to keep a list of things they will need, so I can look at second hand stores ect. When it comes to shoes, I buy new shoes. This past winter hit a little earlier than I was expecting (and will again this year) and I didn't have enough blankets for my kids beds, and ended up taking off my blankets and putting them on my kids blankets. I slept with sheets, 1 blanket and a heating pad, till I could afford more blankets.
If you plan to live like this for a while, you may want to consider house sharing with another mom. I have a 1600 sqft house, with vaulted ceilings, and the amount I pay is low because of a good friend. It's her mothers house, who is deceased, and I just got a very good deal. Unfortunately the college boys who lived in here before tore up the house, so we have been dealing with that, repairing things, sprucing up the place to make it livable.
My van was paid off at my divorce. These are the things that make living like this bearable.
Good luck!
