Interesting topic/thread! When I first joined PC a few months ago, I don't think I filtered myself very well. A thought-provoking discussion occurred in the depression forum about encouraging, in a sense, depressed individuals by posting "I understand how you feel" and similar sentiments. I think I was guilty of that, although I meant well.
I get frustrated by not having the knowledge, experience, or even the "right" words to console someone who is clearly in pain. (That said, a big THANK YOU to you, Theodora, for your kind response to my agonized post in the Relationships forum a few days ago.)
I also find it hard to stay on top of this forum, because it is so big and "moves" so quickly. I feel guilty, for example, responding to some posts and not others, for fear of looking like I am favoring some members over others, when that is actually not the case at all.
I will have to give more careful consideration to my own posts and explore what they say/indicate about my own mental state.
Again, interesting thread!
P.S. I tend to edit and delete a lot, too! Glad I'm not the only one who does that.
