My advice really is to try to focus on consistent behavior. If you see soemthing happen once or twice, I wouldnt put much stock in it... good or bad.
If you see something happen regularly or something stop for along time that I would consider something to focus on.
Today, I dunno... I would just keep a goin. I think you're doin good... Illness is a time to offer support to your family, when you drop off flowers and they come by and see those you will be doing quite well I think... its a chance to show them both at the same time that you give a damn.
