I was pretty nervous at first, even though I had no intention of posting anything identifying. So I certainly empathize.
Practice has helped. A generally supportive community has really helped.
Speaking of which, there is
TishaBuv who was friendly and encouraging in response to one of my earlier harmless but quite silly posts in this very subforum.
I guess I tend to front-load my anxiety by carefully vetting and editing my posts before I hit submit. But I shouldn't worry so much. We all make mistakes. We've all said things we later regret.
How about a friendly hug?
