Hi...I Am Drinking A Lot Of Water And Feel The

Hi...I am drinking a lot of water and feel the urge to urinate but when I do, I do not release as much as I feel my bladder is full. I am diabetic and have been for years. I am experiencing extreme thirst (as I have for years), but that has subsided some over the past few months. I have been extremely thirsty again the last few days and drink water throughout the day. I have no burning sensation and when I do urinate it is typically relatively clear. When I finally did go to the restroom today, it was dark yellow but I believe that is because I had not been able to go for so many hours. Can you give any insight?
