Good life and negative feelings

Mmmm, a hamster in a perfectly happy circumstance can suddenly commit suicide, huh?
If a creature with such a limited mental capacity has that much complex emotions and impulses, think of how it would be for a human being... (No offence to humster lovers, but no one would insist that humsters are famous for their deep reflexion on the truth in the life? )

This somehow reminds me of my mom. She's been a happy housewife with a loving husband with good job, and two smart, pretty, well mannered daughters (of course one of them is me... he he he). But after her daughters left home for their own adult lives, she fell sick...with depression.

She had had a good life. Most of the people would say that she still had a good life even when she became sick and hospitalized. But she was not happy at all... I think I understand some of the major reasons of her negative feelings in the seemingly nice and comfortable life. They are inside her, they stem from the way she had structured her life, the way she set the aims in her life.

I'm not sure if you understand what I am trying to say, because I am not providing details sufficient to have you understand... well, I guess what I am trying to say is that the piece about carrot and coffee Yasir brought from somewhere is somehow right. It is not circumstances but your attitude that constitutes happiness.

Having seen her suffering closely, I am very careful (or at least trying to be) to structure my life... I think three of us are now in a sort of crucial stage of life in terms of designing our lives. A lot of choices we make in coming several years would make a foundation of the life afterwards.

I am happy that I am spending this important period in here, with you, with my work...

By the way, my mom has recovered and now enjoying her ever happy life.
