You may be confused by the way others are acting today, but you cant control this so focus on your own objectives.
Those around you will act in a way that confuses you today and you may feel paranoid and vulnerable because of this. Whether this is a genuine issue or just a perceived one remains to be seen, so for now try to distract yourself. Concentrate on what you are doing and what your objectives are right now, you cant control what others do only what you do, so stay focussed.
