Welcome back and congratulations on all the wonderful things happening for you both currently. I am very happy to hear that your new home has brought you some relief overall, and that your management has been easier lately!
I am sorry that your current wait for your test results is kicking up the old what-if/fear of the unknown worries...but this is a situational issue that will soon be in the past...and you'll be back on track again very quickly.
As Hibee said, use your coping skills to get you through. From the Resources, the Health Anxiety material is good to review...as well as the Positive Mantras link, and the Therapy Worksheets to help tame the most troublesome of negative thoughts.
Keep us updated so we can keep you in support...and celebrate with you when you get the good news back from your doc.
