It's a horrible feeling - and I'm sick to my stomach most of the time (hence the 20 pound weight loss in 3 months).
This is the typical LBS diet. You must take care of yourself first. Maybe you wanted to lose weight but I am sure it was not going to be this way. Think of being on an airplane that loses cabin pressure. The first thing you must do is put on your oxygen mask. then you can start to help the people around you.
It is the same thing here. Worry about taking care of you first. Then when you are in a better place you can worry about others!
