I guess the difficulty over the internet, is that we are only reading words and whether it is the OP or others responding, we know limited things about them and do not always know how vulnerable they may be feeling. My T can say something to me oneday and I may be very ready to hear it, on another day I might find it completely overwhelming and crushing. The other obvious difference being that T is then there to pick up the pieces. We don't know what support beyond T's people may have on here.

I guess there's no perfect formula, but personally when posting I often ask myself how I'd react if T said to me what I'm about to post to someone else.
