Complete nipple/areola loss due to necrosis...what's next? (Photo)

I've suffered total nipple/areola loss due to necrosis and I'm freaking out. The bottom incision has opened up as well. My PS has debrided it twice over the past 2 weeks, prescribed antibiotics, saline dressings, and recommends an eventual skin graft to both areas followed by nipple reconstruction. She says I'm not healing well and very slowly. Is there anything I can do to help the situation? What should be the next step? Is it safe to do scar treatment on other (left) breast during this time?
