Seven years on and feeling anxious again

Hi my name is Jayne.  Seven years ago I was diagnosed with Grade 3, Stage 2 TNBC.  I had a lumpectomy at the advice of my surgeon and oncologist and also had 29 lymph nodes removed under my right arm with five positive.  Eight cycles of chemo and six weeks radio rounded out the treatment and since then I've been well.
In December last year I got my 'no further appointments' from my oncologist.  In June this year I saw my surgeon for the usual annual mammogram and ultrasound and I had three nodes enlarged under my opposite arm.  A core biospy came back as all clear, just enlarged nodes and the surgeon ordered another US in six months.  A couple of days later I came down with a pretty crappy winter virus.  That last about three weeks and I've been well since then.
Last Thursday I went for my follow-up ultrasound and having had numerous of these (like everyone else), you know when they are measuring.  A naughty look at the screen confirmed what I thought, enlarged nodes still (don't know how many).
I'm seeing my surgeon tomorrow but I'm going out of my head with anxiety about what this might mean.  I suppose I'm just looking for some sane words to sooth the negative thoughts in my head until tomorrow, when I'll probably be off for another biopsy.
Thanks for reading <3
