I'm afraid to say, your snake has the Sendittome syndrome. If you would sent it to me, I will bring it back from dispair.
Seriouisly, I think you should be okay. Many snakes will go off their food for some time. Some snakes never stop eating, others will stop for just a short time, others can go without eating for 2-8 months.
Just keep an eye on him. Always make sure he has water. Of course keep up on the temps and humidity. Make sure he doesn't lose too much weight. This is a stressful time for the owner, but everything should be okay.
