Cannot Eat. Not sure what to expect.?

My wife and I are going though marriage problems. We have 4 children. I am not sure what her plans are - not sure if she wants to leave me or work out problems - and she does not want to talk about it. Here is my problem and question. I have eaten exactly 3 meals in 8.5 days (the last being 3.5 days ago) as well as eating a small snack cake about 12 hours ago while being able to drink a soda. I have not drank an entire glass of water over the whole time - just sips here and there. I know that not eating will cause major problems, but I just can't find it in me to put anything in my stomach. I feel sick as soon as I do. What should I expect if this continues? When should I expect noticeable side effects besides weight loss (already lost 10+ lbs)?
