DCIS

I am absolutely freaking out today! 

Still have to wait until 15 July for re excision and SNB.  How do you all hold it together?  To make things worse, the top of my scar became infected, the nurse at clinic on my wound check pulled out the top stitch.  It is not large, about 1cm, but ha something called Slough in it. GP put me on antibiotics, which have helped, but this white Slough still there and I think it impedes the healing process.  Going back to doc tomorrow, as I need it sorted, I can't not have the surgery on the 15th!  Freaking out big time on SNB too, as I'm scared of the results of the lymph nodes, since they found 4mm invasive cells in the DCIS.  Taking Arimidex.  Had a melt down tonight, I'm not doing very well am I?
