A month of two ago we had a discussion about what to say when people ask how you are - it seems alot of times its just to be polite. One of my favorite answers (one i've now adopted as my standard answer) is "no better, no worse." Then if they are interested, explain/expound away. but yes, it is frustrating when friends/co-workers - the people you see day in and day out- look at you like nothings wrong - you must be crazy.
