I might have to disagree with your therapist,and remember this is just an opinion.
By you not going back to work,then you are going to be home everyday with nothing to take your mind off of your problems.
Going back to work,and seeing a weekly paycheck I think will be a great boost in your ego.
I got out of a very abusive relationship in 2001,and it has taken me quite awhile to get out of my rut.
But,it can be done.
Like Carla said all you can do is take it one day at a time,but make sure your own personal needs are met daily.
As far as the X, people that are abusive love control.And by you leaving him he lost all control. So,sending nasty little emails like that in his mind is giving him back some of that control.
Put him on your email block list...or make his emails go into your junk folder. You do not need it.
Do not answer the phone,and if you see him on the street walk away (make sure you get to a safe place).
It is easier to get back on your feet when they are not harassing you...
