Frustrated

So when I called the hospital today to chase results I was told they were relying on PET scan results and will call me next week. They said 2 weeks max. Now I have another awful week of waiting. Still unable to eat. Still without a clue what is wrong other than it could be cancer. I'm so frustrated. I know having all the results means the whole picture and that's good. Just don't tell me the PET scan isn't important and I will get my other results if this definitely is not the case
