Maybe start little by little. For example, drink some water and if you can a little portion of fruit (maybe those that have a high percentage of water would be better), and then try with nuts and seeds...
Maybe you are really stressed because of your new environment.. Try to relax, listen some music and have a positive attitude... I suggest you eat fruit that can be easily digested and not waffles since you haven't eaten so long and make you sick!!! I hope this helped!! :)
I don't know much about it, but it sounds like anorexia. I suggest you google it.
