hi, i have understood your concerns,, and in my opinion u shud discontinue your antidepressant medication until u have appointment to your treating psychiatrist.. u must be given antidepressant medication for your depressed mood and sad feelings, tiredness, decrease concentration. but u may be having hidden bipolarity in you, which can be precipitated with antidepressant meds, which can switch your mood from depressed to euphoric within a month of taking it.. it is called as antidepressant induced hypomania or mania.. your psychiatrist will give u a mood stabilizer for stabilizing your mood, which fluctuating between dysphoria and euphoria.. i hope u ll find this advice helpful.. best luck
