Strange, I'm the opposite. I'm more uncomfortable about posting here because we are specifically discussing SP/SA and its symptoms. I feel as though everyone is judging my grammar, spelling and opinions and trying to find fault with them. Ironic that when I'm trying to work out my fear of being judged by talking about it in an SA/SP forum, I end up obsessing and worrying about it more.
As to the original topic, yes, I find I take entirely too long to post a reply. I edit and spell check so much that by the time I'm done it seems hours have gone by. Sometimes I will even forget what the original topic was because I take too long worrying over my grammar and spelling.
