PCOS frustration

Don't really have a question; just need some support. I have been diagnosed with PCOS and my doctor had me try metformin. It made me so sick! Now I had an HSG done and they told me that one of my tubes is blocked. I know that I need to lose weight and have been trying since April 2014 (no luck with the weight loss).  I'm going to try a diabetic diet plan so hopefully that will help and I can stick with it over the holidays!
