hello, It s almost clear that you are having relapse of depressive illness & it is not just bupropion withdrawal. You may try green tea, eat more fruits and green vegetables and go for more walks and become social. But if the symptoms increase then you should start anti depressant as- delaying meds will only make illness more severe and difficult to treat. It may have happened that the bupropion was stopped before completing the normal course of medicine. whenever the patients stop the drug or reduce it in hurry( even after 100% response the drug should be continued for few more months as directed by psychiatrist)-- they are most prone to develop a re apse of illness. There is chemical imbalance or shortage which results in depression etc. , and meds help to bring back that balance. Hope the reply is helpful Have a speedy recovery!
