Doctor visit

I went to the doctor today and received news that I was not happy about. My blood sugar is no longer under control. I now have to be on a very strict diabetic diet. No sugar, no refined carbs. No fun food. I have to exercise 1 hour a day, 6 days a week. And he doubled my prescription. There is another medication that he would like me on, an injection. Except my insurance doesn't pay for it and it costs way too much... Soooo... now what? I don't know. I just can't afford it. Hopefully this new diet and stuff will get it under control and when I go back in 2 months he will say I don't need it. This totally sucks. But it could be worse. But I am worried that I can't do it. It is such a daunting task. I know I will be miserable. I just hope it works. I hope my blood sugar evens out and I lose weight. That is the goal. If I lose weight all of this will probably go away. Then no more health worries... Right???
