Hello and welcome to Healing Well and the Depression Forum. You will meet many wonderful and caring members here who know where your coming from and what your going through.
You did not mention what dose of Cymbalta your husband is on? Also does his Physician know he spends all his time in bed. IMHO your husband is in serious trouble if he is so depressed that he stays in bed 24 hours a day for a month.
Does he get up to eat, bathe or what does he do in bed that long?
I understand how frustrated you must be and hope you see a therapist or someone just for you.
Please keep posting but perhaps a bit more detail might help in providing you with advice. :)
Again a warm welcome.
