We have had a crappy year as well to put it nicely. Here is what I try to focus on so I don't go into full panic mode. It's temporary- you aren't going to the spa, buying your kids designer diapers and blowing money you don't have. You are both working so you have income to pay your bills and while you'd like to live more comfortably, it makes you realize how much excess you've had in your life and what is important.
Make a goal that six months from now to be in a better situation, and a year from now an even better one. You also need to focus on having healthy kids and a healthy family, a yard for them to play in, a beautiful home, etc- this is what my mom always does and talks about the wounded soldiers coming home with no legs. I always think she is crazy saying this, but she is right. I hate that you need to know someone with a truly sick child to realize that other things don't matter as much and truly appreciate what you do have.
If you are eating out, it's easy to freeze crock pot meals for the week to make dinner easier on you and the budget. Good luck, you aren't the only one out there struggling.
