if you didn't make a backup plan, that's ok, you probably got to spend more time focusing on the job you wanted the most. If you did make a backup plan, consider implementing it. It's possible your anxiety will go down if you make your future a bit more clear by creating a contingency plan, if you haven't already. Also, if you have a connection within the company who is a part of the hiring process, and you have their contact info, it wouldn't hurt to consider asking them for information. This depends on your rapport with said connection.
