I'm sure your priest will understand. You sound like your religion is important to you and your fast is no doubt at least partly for spiritual reasons anyway.
The good news is that although your fast was technically broken, it wasn't a complete stop and start event. Your body would have been confused and energy would have been diverted to the digestion system so the fasting was certainly interrupted but full ketosis would have been returned very quickly if that's all you did to break it.
