it could be the effects of the med kind of causing the feeling of indifference. I would ask your doctor about the potential effects of the medication as many meds of the psychiatric kind can give a kind of blah feeling to the mind. It is also very possible that the anxiety could be causing it as well. But if the only thing that has changed in this scenario is medicated versus unmedicated, i would explore the possibility that the med may be having this affect on your mind.
