<s>[INST] I am a 18 month post da vinci prostatectomy cancer survivor. My 18 month psa was negative. My issue is that I still have depression from post surgery issues. Especially sexual issues. My PCP has perscribed welbutrin which I have been taking for two months now. I am looking for advice on SE MI support groups or forums. [/INST] Hi, Good to hear that you are doing well post cancer surgery. Can you elaborate your symptoms of depression? To the best of my knowledge & experience, Wellbutrin (bupropion) is a very good Chat Doctor.  & it doesn't cause sexual dysfunction by itself per se. But if symptom profile is predominated by anxiety & allied symptoms which I guess are the source of your troubles & probably sexual dysfunction also; then switching Wellbutrin to a more specific antidepressant alternative like Mirtazapine which works superbly for anxiety & allied symptoms, gives you good sleep as well & is neutral on sexual dysfunction as a side effect. Hence, do discuss this alternative with your doctor for symptom relief. Good luck </s>
