I went to a Celine Dion concert (not quite the same as Skrillex, I know) by myself. Hubby had no inclination to go whatsoever. But I grew up singing her music and she has had a huge influence on my singing "career". So I buried my anxiety deep. And went. It was exhilarating. I managed to find my way out of the concert when it was over and walk the distance to where hubby was waiting to pick me up. I didn't think I could do it. It is something I'll never forget.
