Hon, fasting will detox your emotions, too. Not only does the physical body remove unhealthy toxins, but the emotional and spiritual bodies remove unhealthy toxins, as well.
I would say, you've been going through some heavy wholistic detoxing... wholistic as in detoxing your entire being... everything purged.
Sometimes physical detox can feel like hunger... in any case, I am very glad you're feeling much better. It's a very good idea to take time each day for prayer and the uplifting of your spirit.
