Too Sensitive?

Some of my friends keep telling me that it's time to "get back out there" (i.e. dating). But, then I have days when I feel like the Mailer-Daemon return service on my e-mail sounds like it's breaking up with me. (After all, it does say, "This is a permanent error. I will not try again.") And, on those day, I think I'm not quite there yet.
