<human>: Last week I interviewed for a promotion opportunity at my office. It's a position I am well suited for and I would love doing the work. I walked out of the interview feeling great as I think it was one of the best job interviews I have ever done. I answered every question, had questions for them, and it seemed very conversational. At some point it was as if they were speaking to me like I already had the job. I was also sure to write a thoughtful well planned " Thank you note".

They said it would be at least a week or two before they made their decision and that there was possibly going to be a second interview. I've started stressing out big time. I am having trouble sleeping and concentrating on my work. Any advice for how to deal with the stress and worry that comes with waiting on the results of the interview?
Thanks
