It is really terrible when people say mothers don't commit suicide because of their love for their children. Think about what you are saying. Think about who is reading that. It happens all the time. I put the statistics out there, go look at my profile and read the post, and you can go find the stats for yourselves.
The most common cause of death of women Elisa's age is suicide. The majority of women in their 40s are mothers with still dependent children.
There will be people reading this whose mothers have committed suicide. Are you saying their mothers did not love them? If they were mentally well, they would not leave their children via suicide, plunging them into grief. Their mothers loved them, and they committed suicide, they are not mutually exclusive.
We have children and a will to survive by design, the preservation of life is a strong force. In some instances a desire to die is logical - in the face of terminal disease with no quality of life. But for the majority of suicides it is a glitch in the machine of the brain, and no love for anyone or future plans or having your dog with you or not can correct that.
