I get the butterflies in the pit of my stomach just thinking about all of the things that could've gone wrong. I think the anxiety mostly just centered around losing that safety net. It was easy to see once I was on the other side how limiting the job was though and all the ways in which it detracted from the quality of my life. I think I might know what decision you're speaking of. It's never an easy thing to make that decision about a pet. It's good that you don't regret it.
