emotional shutdown

Is it possible to shutdown emotionally when a person get over stressed and theres no escape. I have a Bipolar partner and sometimes things get really tough and blown up.I try to walk away to calm down but she follows and demands,even threatens me to know "why" If she doesnt like the answer she just keeps on me.Somedays ...most days I have such dread knowing what I'm coming home to. I feel sick and feel I cant function and have no emotions to try to resolve issues any longer...help

be very careful you maybe become sick,thats what happened to me i was living in chaos 24/7 no escape stress at work at home with my daughter etc i finally broke 3 months ago were i could not function i just wanted to run away,please try get more support for your partner and you must take time to yourself for your own mental health,good look my friend i have two friends who have partners with bi polar and they say its so hard.
