basically what it comes down to from what you said above, is that nothing makes anything feel better, only worse right now, when you discuss it or others discuss their situations.
And that makes total sense. When I get down about something, I kind like to keep to myself. When I am grieving something and don't want to hear the expected responses because I know they won't make feel any better at the time, I keep to myself.
You are grieving. You are going through a very normal process. Do it the way it feels right for you.
