It should only be talked about if the talking will make you feel better. It is of no value, ever, to activate and talk about something that doesn't feel good, because it reactivates it in your vibration; it makes it another point of your point of attraction so you're less clear.
In other words, when you focus upon the problems of others, you diminish your ability to help them. People believe that you've got to focus upon the problem in order to find a solution. And we say, no solution ever comes forth - it's never inspired; you never recognize it, and you are never able to facilitate or achieve it - from your place of focusing on the problem. They are two entirely different vibrations.
If you have someone who has many things going wrong and one thing going right, beat the drum of what's going right, and let that be your point of attraction. If you focus upon their problems, you achieve vibrational harmony with something other than the Source that gives you solution.
