I will write almost the same that I commented on your other thread because it's basically the same question:
Desperation and impulse can make ctb anyone.
When life really overwhelms you, you'll try to go for it.
At least that's what I did last year. I was desperate and scared but there was no other way out. I had to do it and I did.
Unfortunately, I only got a 2-day coma, 1 month in hospital and 5 months in prison (my parents house).
