what makes ppl commiting

A close friend's wife committed suicide a few years ago. They'd been married for 4 years. She was very young. I still get jitters when I think of her and everything that happened.

It was very hard on her husband and her family.

Now, I could sit and argue about how she could have handled all her problems, but the fact of the matter is that she did not share her mental state of mind with anyone, no mediator, no counselor or physician. Maybe she could have been helped.

Allhamdullilah, I have never been in a situation to think like that. I'm not sure what goes through the minds of people who do this.
