It's sad, and I won't delve into the truth of this story.
I'll say this from personal experience. I don't want to blame the system, because the topic is relative, but I can be certain of one thing: your friend must have suffered from long-term depression. People can hide depression so that you don't notice it.
Nobody commits suicide overnight.
especially not for such a trivial reason, which is an everyday occurrence for people. It had to be, at most, the final trigger.
Many of my friends have committed suicide, each with long-term mental health issues.(even my grandfather hanged himself a few months ago) I've struggled with depression for 60% of my life, and I've had countless suicidal thoughts. Fortunately, I've long since overcome that (although the depression still lingers deep within).
To escape this, people took drugs, medications, alcohol, and any other substance to numb themselves. Even gas to lighter(I don't recommend it, slowmo, like you're dying, something shit feeling like when Kurotsuchi, Mayuri slowed down the pace Grantz, Szayel Aporro.)
suma sumarum it is like a cancer that must be overcome with a strong will as steel.
Attitude, the environment you live in, ego, many relative things, sometimes it's worth thinking that you could have it worse, sometimes it's worth changing your priorities, sometimes it helps.
I could write a book about it and then I realize there are people in much more fucked up situations than I've experienced.
in my life, no father, no mother, orphanage where a nun tortured children, these are just a few percent of my life.
which gave birth to this "cancer" in me.
But we must live with this, not haved choice bro.
So don't blame places where the problem definitely isn't, because believe me, you don't even know why it happened. Worse still, thinking about it makes you depressed.
