Its very hard for people wwho have never suffered depression or mania to understand what goes on inside our heads when we are down or manic.
My advice, from a person who suffers BP and also deals with a with a wife who has bad depression is to learn to let it go. I just don't take it personally when she is upset, and i understand what depression is and how it affects the mind.
Acceptance in the end is what allows me to live with her. I understand that she isnt doing this just be mean, its a chemical imbalance that she has very little control over. SO when she is down i help by doing what i can, but in the end i let it run its course and wait for her to come back to me on the other side of depression.
