Cancer's back and a sneeze broke my back!

I was diagnosed with breast cancer on May 15, 1006 (3:30 pm).  After a mastectomy, chemo, radiation and 4 reconstruction surgeries I hoped I was done while realy not believing it.  From all the reconstructions, I had persistent chest wall pain and my wonderful oncologist sent me for a bone scan.  Everyone involved, except me, was sure this was a waste of time, there would be nothing there.  In part they were correct.  There was nothing on my chest wall, but they did find a tumor in my spine (T11).  After many tests, I can't believe people could'nt see me glowing on the horizon, I started teaching this year as usual.  New school, new kids and faculty members.  This really didn't last too long.  While getting ready for church on Sunday, I bent over to get my hair dryer and sneezed.  Oh the pain was immediate and extreme and I went done like a ton of bricks.  Amazingly I was able to get to church where I met my Dad who took me to the ER where they found that I had indeed cracked my vertebra where the tumor had been living.  For the next 2 weeks  I went in and out of the hospital where they eventually removed much of the tumor and performed a veterboplasty to repair the spine.  While in the hospital my friends called to check up, but no visiting.  Since I've been out even the calls have slowed down.  I know cancer is scarry, but do friends realy have to run away from it?  They know they can't catch it and I know they are busy, but I have been there for them and they need to do the same.  What do I do to feel stronger, survive the future treatments and not do these things alone?
