Hi, Overactor. I'm sorry to hear of your health troubles and that your health is getting progressively worse because of lack of health insurance coverage. It is awful that about 50 million people in the most developed country in the world do not have health insurance coverage. We can only hope that this will get better...
I would suggest that you do lots of research online. There are many organizations that may be able to help pay your medical bills or at least guide you to others than can. The American Heart Association, American Stroke Association and the Larry King Foundation are three that come to mind as good places to start. Internet searches can provide you with a wealth of information. Start contacting and applying to as many of these places as you can. Try to make a compelling case as to why you need this treatment and how you can't get it because of lack of insurance coverage. Oh, and that yeah, your life depends on it.
I wish you the best of luck on your difficult journey. We are going to be here for you providing support and encouragement whenever you need it.
