What did two weeks off from running do to me? Will I survive my first run?

In order to prevent further injury, I took the past two weeks off from running.  It was hard to do, but I was worried that I had a stress fracture.  If I do have a stress fracture, that could cause serious problems in my plan to run the half marathon in September.  They recommend a bunch of rest to allow time for stress fractures to heal.  So, during my rest, what happened?  A few things.  I gained back about 4.5 of the 7.5 pounds that I had lost.  I ate alot of junk during my time off (by the way, if anyone has any easy, healthy recipes send me an email!).  Obviously, regaining the weight made the beginning of my two pack disappear. 
On the positive side, I still have not had a cigarette.

I am about to go do my first run in two weeks.  I think I'll try to do two miles.  I'm a little nervous about the test run.  If I still have pain in my shin, it could mean that I have to take more time off.  It could also force me to actually go to the doctor.  That is the last thing that I want!  I'll post the results of my run in a bit!  Cross your fingers!!!
