AAAAH! Thank you for the update. No cancer or masses, what great news-)
The test results for Addison's are not in yet, so don't get stressed about that until and if it happens! As you say, even if that is the diagnosis it can be managed, and you can live with that.
I am sure you will find a food she will like and that will keep her well.
Hope you feel calmer now and that you look forward to picking her up and giving her lots of hugs and kisses.
It has been a tough week, but all will be ok now.
Get well soon Sophie
Hugs.
