I guess that people are just cautious about saying anything when the picture posters have expressed such strong (and often very sad) emotions. But I think that discussion is a good thing, as long as we aren't being unkind about anyone else's pain.
It can be very difficult to know what to say sometimes.
Any subject is suitable for confession--have you noticed that no one has confessed to being happy? :look: I find that interesting.
The Picture Confessions don't necessarily have to express something fierce or terrible; it could just be about anything that is on your mind that you don't want to say out loud to anyone.
