I've started maybe three topics ever in the just-over-a-year that I have been on WP. Two had responses from Kortie and Bea who are always kind, and the other post had only one response.
What I am hearing is that today you decided to get some new online friends and it didn't immediately result in responses, so you deduce from that that you are a nobody. As many here have pointed out, that would be faulty reasoning. You aren't nobody here.
A long time ago, when I was still trying to fit in, I went to a party. I really did not want to go, but it was go with my (now ex) husband or spend Christmas alone. (this was back when I still thought that was important.)
As one might predict, I felt totally left out among the revellers and snuck off into an empty room to read. I turned on the light so I could read. A bit later, someone looked through the doorway, looked straight at me, and said out loud "There's nobody in here, so I may as well shut off the light." And she did.
I sat there totally astounded, confused. After a while I got up and walked home through the snow. My now-ex husband never missed me.
So much for being nobody.
