PET scan...

So this morning was Wayne's PET scan.  We have an appointment on Monday to find out what's going on.  I'm feeling very anxious about the results.  I want so much to feel positive that all of the treatments for the last 9 months have worked, and he'll get a scan that is clear of any cancer cells.  I want to believe that.  One part of my brain keeps telling me to think positively.  Positive thoughts bring positive results, right?  Then the other part of my brain is scared and fearful that it will not be clear.  I don't want these negative thoughts floating around my house and wreaking havoc on his cells.   I want them gone!  Go away negative thoughts...go away.
