GOOD NEWS! He actually called me back a half hour later and told me that he definitely wanted to put me to work and in training for next week, and would have his assisstant email me the hours in the next few days!
I mean, I don't technically have the job yet, and could lose it at any point for now, but WOOOOOOOOOOOOOOOOOOOOT!
phewwww. at the very least that took care of the anxiety.
