Hi L.,
I have 4 children, and was single most of the time since they were born. My daughters were 7 and 9 when my son was born, and he was almost 6 when my youngest was born. I was single up until 1 1/2 years ago, when my youngest's father decided he wanted to be a family, we aren't married yet, but living together. (And my oldest just moved in with her father so she can go to college!)
As a single mother, I did well with my kids. It was harder financially than it was physically and mentally. I loved having that time with my kids, I was a SAHM most of the time, going back to work after the youngest was in school. I was a much better parent when I was alone. (nobody to argue boundries with, punishments, eating habits, cleaning habits, and homework. I had control of all of it, no fighting in front of the kids, is a much healthier environment for them)
I did have financial assistance, food stamps and cash, and I worked part-time, until the kids dads decided to pay support, then I used that to live instead of cash assistance, but still had food stamps and medical for me and the kids.
When my son started in pre-school, I was offered a driving job for the school district, by a private contractor. I have been driving for 5 school years, going into my 6th in August, and I love it!! I have been able to take 2 of my children with me to work. My son before he started kindergarten, and now my daughter, she's almost 3, and she will ride with me until she starts school.
You should first check into unemployment, if you are not eligible, go to your county assistance office and get help from them. They will get you started, and send you to job search classes, do up a resume, and give you info on jobs available.
Also, check into your county/state housing authority!! There is usually a waiting list (months or years in some cases), but its worth it. Apply anyway, get your name on the waiting list, when your name comes up on the list, you decide if you need it or not. There are also ways to get your name moved up on the list, ask questions. (eviction for nonpayment, you need proof. change in income, like losing your job, stuff like that may help you to get help a little faster) Also find out if other agencies can help you get moved up faster. It is one less thing to worry about with a new baby on the way. You will also be needing another room if the new baby is a girl! Housing will cover that.
Good luck
