You need to educate yourself on mental illness

You don't understand what mental illness can do. Depression is a mental illness (Diablo iii Gold). We aren't talking about "I'm feeling a little down today" but a severe case of CLINICAL depression.

It's a medical condition. It's also pretty obvious to others (though not to the person who has it, due to their mental state). So why did no one else notice the problem and help her before it was too late?

If she were on the floor, incapacitated with a stroke (Diablo iii Gold), people would blame themselves for not checking on her and the kids, for not noticing there was a problem. Same applies here. She was mentally unable to function and it WAS something others should have, and probably DID notice.
