Hello,
You state your "spouse is depressed" - I was wondering if this was indeed a clinical diagnosis from a psychiatrist, or mere speculation...I agree with other answers in this forum that your spouse should be seen by a professional who can help to put her on the road to recovery in terms of mental health...This forum is good for quick answers, however, your spouse needs medical care.
Having said the above, the symptoms you describe can be due to OCD - and if so, that can be addressed and handled according to your spouses needs, i.e., "therapy; biofeed back; and medication." - The depressive individual presenting with OCD behavior can be successfully treated, and the sooner the better before it develops into further decline.
Good luck, God bless you both~
