I am sorry to hear that you are having a rough time. Please do not feel that you are a burden to your doctor!! It's his job to help you. And right now you need some help. Don't hesitate to ask for it. You might need additional medication for PMDD. It's not uncommon for women to have a difficult time with that. And even more so when you are already stressed and struggling with depression. Ask for something to help you during that time. Explain to the doctor all you are going through during that time. That it makes it nearly impossible to work. There is no doubt in my mind that he'll help you.

What medication are you taking now? Does it help the rest of the time? Are your symptoms milder? Or do you feel that it's not helping at all?
