Why dont you order some Meal Replacement Drinks that are easy on your stomach and provide you with nutritional value?
But, besides, you may give thought to take the shortcut to reach out for help. If you call a helpline, these people knwow what to do and you wont be their first rodeo. It is perfectly fine to reach out for help, even it may not be easy, but then again, it won't be easy one or the other wy, so what are you waiting for?
Also, you surely will find inother forums some user experience comparable to yours (e.g. no energy to clean up) and get informed, which steps these guys have been taken to a step by step solution.
I personally think after reading your posts you need to change your focus towards getting to action and not seeing all the problems and the nos of your situation, even when this is simple but not easy. But others have manged, so you could do.
Just think "what if I can do this" What if!"
All the Best!
