My wife appears to have lost any interest in going out or doing things that she can't do in bed on her smartphone/Kindle. She spends so much time in bed that I'm beginning to worry about bed sores. How can I tell if she is depressed or needs professional help. She never goes or is willing to go to the doctor for anything short of life-or-death situations. I don't think I could persuade her to get therapy, but it is having a big impact on my life satisfaction.
