look to see if there is a Jewish Family counseling service in your area. You don't have to be Jewish, the name is a nod to the origins of the organization. They work on a sliding scale that is VERY generous. It goes as low as $5 per session.

If there isn't one, call a crisis hotline and explain the situation and that you're looking for solutions that you can afford. Crisis lines are almost always funded by the number of people they help, so don't feel like you're being a bother. That person can help you track down resources that are available where you are and are in your ability to pay.
