help with my bills and mortgage

$200,000 I have been working fulltime until recent my husband has started his company a year ago that is not making much money, we are living off our equity which has $5000 or less left. I am going to lose everything if I cannot afford to pay my equity interest let alone to have money for food and mortgage payments. I have 4 beautiful kids that I support and would hate to have to disappoint them with having to sell everything that we have earned. Somebody,anybody please help me and my family, I know that when I put that amount in it sounds like a lot but I need to pay all of this back in order to stay alive.
