The car bit me on the budget again last week. It's annoying but not impossible to deal with. I will just go into strict mode on spending. No eating out or going to the store for a couple weeks. I've got food in the freezer for work lunches and we have a good supply of all basics (pet food, etc.) so there shouldn't be any problems.
It's times like these that I wish I had started the debt payoff sooner. Half my income goes to debt and mortgage payments. Imagine how much easier life would be with that available. Fourteen more months until it's all paid off.
