How do you deal with a sick spouse; when they are in great pain or suffering? When is nothing you can do to help, nor have money to get them the medical attention they need.

My wife is young 32, however has a lot of health problems. I do everything I can for her from helping with housework, cooking, taking care of our son. Also I try to buy her medications when she needs them; however she has no insurance and I can't afford any for her. I hate watching her in pain, I cry and watch, and pray. That's all I can do.
