How much do you make, specifically net income? In which state do you live?
You don't have a lot in assets and those you may still have may be exempt from seizure. BUT in most states if you make more than the exempt amount of net income (gross minus certain deductions), your pay can be garnished, even if the income is still low. This exempt amount per Federal law is the Federal minimum wage x 35 hours a week; some states allow for a more generous amount and a handful do not allow wage garnishments, either for all wage earners or a head-of-household such as yourself.
If you have a bank account? That is almost certainly vunerable to seizure. All too often, even if the funds all are exempt from execution, a bank will take the "safe" way out and freeze the account and let the judgment creditor take whatever they are allowed to take. The debtor must then go to court to try to get the execution reversed and the funds returned, a procedure that takes time and money.
