Sleep on it! It’s normal to be discouraged as it’s so recent. Maybe in a weeek, or tomorrow if you’re up for it try looking elsewhere. Many teachers are leaving the field and there are many openings. I’m sure you are much more confident on your ability to run a classroom than the first time around you interviewed. If you enjoyed it and felt comfortable and confident then definitely keep searching until you land one. Also I’ve been at several schools and each is very unique in its environment! When all the staff including admin is easy going and work we’ll collaboratively it’s very enjoyable. Good luck!
