[/INST] Hello, Thanks for choosing Chat Doctor for posting your query. From the description that you have given it appears that you are having a recurrence of depression. Your complaints of nausea and tiredness can be a part of your depressive symptoms. Although you are already on 100 mg of Wellbutrin, you still can have a recurrence. Your psychiatrist may like to change your antidepressant and also add mood stabilizer as you are having a recurrent depressive disorder. Also in old age it is advisable to get your electrolytes and thyroid hormone levels checked. Besides consider starting sessions of cognitive behavioral therapy with your psychiatrist. Lastly good diet and regular exercise go along way in maintaining your health. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you.
