Had x-ray of chest. chest is fine but spine showed "mild arthritis!" im only 32! have untreated anxiety n now terrified over this. what will happen?

Probably nothing, : Best thing to do is exercise ona regular basis and keep in shape. You might consider a trial off milk(intolerance often associated with inflammation_arthritis a common form of inflammation)-also might help with anxiety symptoms.

Incidental finding: Sometimes when a doctor orders a test looking to make sure there is no lung problem for instance, the radiologist notices something on the x-ray that is completely unrelated to the reason the test was done in the first place. We call that an "incidental finding". If it wasn't a problem for you in the first place, try not to worry about it.
