Just to add, anxiety is a common withdrawal symptom as well. There are many people who went on a med just for depression and developed anxiety during withdrawal, and vice versa. Hopefully this will pass quickly, but it could be you needed a slower taper.
I would not expect shortness of breath as a withdrawal effect unless it represents anxiety that you are dealing with, and that might explain your being short with your family. If it is anxiety, then staying on top of your life problems is the remedy, and you can go to my website..www.shrinkyourself.com for a free 3 day trial of a self help program that will help you.
