Many things can cause how you feel from medications to simply letting your thoughts and fears get the best of you.... especially at night, which magnifies your symptoms.

Are you physically able to exercise and do it regularly? Exercise helps relieve symptoms and gives you a way to fight back beyond just taking the meds. When I feel really bad, exercise makes me feel better even though I may not feel like doing it that particular day.

Have you tried breathing exercises or even yoga to help calm your anxiety?
Are you drinking enough water and taking supplements properly?

It's good that you're working with a doctor on your diagnosis, but you have to take charge and determine what makes you feel better or worse on any given day with any given symptoms... it's not an easy process!

Pay close attention to what foods you eat and drink and when, your physical activity level, and what you do that makes you feel better or worse during the day. Take notes if necessary which might help you or your doctor see a pattern that might otherwise be overlooked or missed.

Hope this helps....!
