Hi Nikki,
Try drinking a relaxing tea such as chamomile or valerian about an hour before bed. This should help to calm you down so that you can fall asleep and hopefully stay asleep.
It is understandable that having no medical insurance adds to your anxiety. Please check with government offices or even by calling a doctor in your area how you can access free health care. There must be options for low income individuals in your city. I hope you find a clinic in your area.
Keep working through the program and post as often as you need to. As you said, posting on this site also helps a lot with your anxiety.
