... Resiliency is the goal y'all. I think that's kind of the bottom line here.
If you find rejection at your door, open the door, be pissed, tell her to go home, and then start with your applications again next year with more determination and fervor than before.
Create a support system within yourself for dealing with grief and rejection. Adulting and (I assume) being an awesome vet requires it.
No matter what the outcome becomes; know you've got it if you're rejected everywhere. You've got it if you decide to apply next year and you've got it if you decide to pursue a different avenue. I think everyone on this forum knows how strong you are already -- you've made it this far and you'll undoubtedly make it to the end of application season, no matter what the result.
Also somewhat related: IMO, lower expectations and being surprised > great expectations and being disappointed.
Hahaha that gif, thanks
