I live with my parents but that doesn't mean I can afford this baby on my own. I can't get any assistance because I live at home.
I don't know what to do and I'm very depressed.
You may be able to get assistance even though you live with your parents. Where I live, you just have to prove that you buy your own groceries (i.e. I assume with receipts?) So call the local office and see if you can at least be eligible for state insurance, etc. if you need it. Can't hurt to ask!
As for you child support, I don't really have any experience with that situation, but I believe he would have an imputed income based on his previous income. I don't know if his going to school interferes with that. Good luck mama!
Since he will have no record of income, unless you can prove his earnings from the under the table jobs, the amount that he is very likely to be imputed will be 40 hours at minimum wage. You will get a child support order. Doesn't mean that he will pay, but you will have the order. And if he gets a regular job that isn't under the table, the support (along with the arrears) can be garnished from his check.
