I am painted black again. He (DBPDH) is attacking me emotionally & I am feeling too weak to battle. I am dealing with some hypertension problems & have had several oral surgeries over the past 18 months so I have not felt well much of the time. Feeling depressed sometimes too. He always seems to pick up on my weakness & hammers away. He is acting as if I am a worthless waste of a human being. I homeschool our 4 children & do the best I can to keep some order in the house. I get no support from him & now he is tearing me down.
I need some refreshers on dealing with this. I'm feeling really beaten down these days

I think it makes sense for you to get a therapist for yourself and get the depression treated. Perhaps a light antidepressant can help turn that around and also the therapy to assist you in finding some skills in self care emotionally.
Its important that you stop the damage by walking away from his emotional abuse. Leave the room, the house...and start listening to your own emotions. When you feel battered, you are. When he starts in with his abuse, look at him and stay " Stop it now" and walk out. Stay out. Dont interact with him until you both are settled again.
As long as you sit for his abuse, then he will keep doing it. It helps him feel better and as long as he has your permission to do it ( by allowing him to), he has no reason to change his behavior.
