Help for medical expenses

well here we go again needing medical treatments as a result of diabetes on my body . I have learned that insurance for some reason does not cover a lot of anything that has to do with diabetes. with such a shame. the insurance companies make so much money off a disease that is so difficult to keep controll of and requires so much medication. I was diagnosed with blood clots in my left leg and was told by my doctor that his treatments would help reduce the size of the blood clots then he could go in and place some stints in my leg. it's just another expensive I can't afford seeing that I am not working since I had my stroke.
