Single Mom w/ $$$$$ Stresses

I am a single parent of a fabulous 6 year old daughter.  Her father is a dead beat - even though he is in the military - and I am stressing out!  I make a decent income, but with mortgage payments, a car that is falling apart (it is in the shop again for the 5th time this month), credit card bills, medical bills, insurance payments, gas, montly utilities, I am barely making it each month.  I'm not looking for something with nothing in return.   I just need some help to finally feel like I can actually put something away.  I still owe $7000 on my car and its 4 years old.  Not that that is old - but it is falling apart.  And my poor daughter - every time we go to the grocery store says "Mommy, do you have enough $ to buy that?  Cause I don't really need that yogurt or cookies or grapes, etc?"  Do you know how horrible that makes me feel???  I just want to feel ok and go to sleep one night knowing that all the bills are paid and I can at least not worry for one day.  Anyone willing to help - please contact me at kwiz0628@comcast.net.
