Good for you B. Kerry. After losing a spouse of many years, it is only natural that the remaining spouse will be totally lost and depressed for some time. But, for goodness' sake, let that person experience the loss of someone and deal with his/her emotions naturally instead of masking them with numbing drugs.
I think if someone were in this situation, and after say six months that person is unable to function, then maybe more drastic measures might be warranted, but only then. And even then, I would try just getting that person back out in society or involved with family members before I'd resort to medication.
For goodness' sake, emotions are normal human responses to life. Why can't people understand this and behave accordingly?
What doesn't kill me makes me stronger.
