Don't start the New Year with a fight, even if it seems tempting and you feel that all the arguments are on your side.It may be better to talk things through and find out that it was all just a misunderstanding.
You enter a difficult phase that may last right throughout February. Stay guarded, keep a low profile and avoid any confrontation.
It's better to slow down rather sooner than later. Otherwise you might wear yourself out or get into trouble. A little rest will also heal your strained nerves.
