First off take a deep breath. Not too deep cuz if you are dizzy you may pass out.
You need to eat something or you will get sick. Find cheap things. You can eat Ramen noodles for less than 20 cents a meal. Sometimes even cheaper. May not be all that tasty but hey, it fills the belly. To make sure my kids have decent meals I have eaten quite a few of those.
I am in the same boat as you. My bills cost more than I make. I got my hours cut back about a month ago and now that my divorce is final I have to file single and that knocks more money from my weekly paycheck. From what I am used to I have more than $225 taken out of my checks each month. It sucks but I will figure out a way to make it.
Whatever you do, don't get a credit card. That is why I am in this mess also. I was only making $8 an hour when xh left and that didn't pay for much so I used my credit cards. I am hoping to refinance my house in the near future (if the market ever picks up) and have my bills put into it and that should help out A LOT! Thank goodness I used my tax refund to pay my car off.
