Are these feeling to do with depression or something else?

I'm In a major depression, that what they tell me. Have very bad emotional numbness and feel zoned out, just started taking wellbutrin, had a bad panic attack that night, stop taking it woke up next day feeling very heavy, hopelessness and tired and bad stomach cramps. had another panic attack. now feel burned out. Should I take this pill again and has anyone felt burnout with depression before, feeling like a robot?
