Cops - "you have the right to remain silent", whats the rest of it?

Here in Yorkshire we would say "bottling it up"..that's a better way of saying it,at least it is here, though your phrase is perfectly adequate, however the actual practice in my view is detrimental to health.

Correct. One could also say,"non-expressive of one's feelings." or "exhibiting repression of feelings (or "dull affect").

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
