One year in but a newbie

[Lifes Twists]

My neighbor and I were talking yesterday. She has known my wife and I for about 15 years. I told her about my wife's suicide attempt. She was aware of most of the rest. She eventually told me that she viewed suicide as the most selfish thing a person can do.
This caused me to think for a while. I had heard this many times in the past but had not thought about it during this past week. I have also heard that a person going through a MLC will be selfish and everything will just be about them. Given the depression mixed with the possible MLC is this attempt, brought on by her illness, the ultimate result of the selfish nature of a mid life crisis? I am struggling to make some sense of what has happened and trying to have something to say t my children that will help to to understand what has happened and what will probably happen in the days to come until hopefully their mother recovers.
