Life...can be happy, trips to the park, beautiful flowers, a kiss from somebody special, an unexpected surprise...life can be tragic, death of a loved one, losing a house, a family pet dying, betrayal..."that's life" could be anything...we can deal with happiness but it becomes a stigma when it's negative. We're allowed to have "just life" when everything is peachy and happy but we're not allowed to have "just life" when the situation isn't very nice..
We are all alive and every outcome that we experience is just life. So to just dismiss any positive or negative outcome of being alive as being something insignificant or something to 'overcome' is meaningless.
I don't think that Anna committed suicide..but I get the impression that she had too much on her mind to make rational decisions. So she slowly broke..everything and everybody broke her down.
Poor woman must have been feeling so heavy and weighed down in the last 5 months she was alive. I can't even bear to think of it. How did she manage to breathe...
