Patient

People who suffer from mental illness tend to go from a different time frame than the rest of us.  When you figure out what time means to them, then you can create a new time frame that will help them cope with life.  If you try to force your time frame on them, their mental illness will come out even stronger.  Learn to be patient and schedule things around them, not you.  They may adjust or they may not, but you can go back to the old motto.  You can only control yourself.
