How can i tell the different between dry mouth and excessive thirst? lately i have been feeling like my mouth is dry and i keep drinking water but nothing helps. i dont feel thirsty though my mouth just feels dry. im worried?

Anxiety can cause one to have dry mouth. If you are under more than usual stress, that may be the explanation. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated.

The way you describe sounds more like dry mouth. Before getting anxious about what might be causing you the problems, seeing your doc and/or dentist for an exam would be a good start.
