I feel the same way. Between replies that ended up hurting my feelings and a general sense that I don't belong here (or anywhere) and that I don't feel like other people can relate to or understand me, I've started posting less and less over the years I've been on here. And when I do post it usually takes several hours/days to convince myself it's ok to do so. I do hope you don't get to the point that you're too anxious to post even when you really want to like I have.
