Yeah, just another symptom of the whole "gotta be macho or else I'm not a real man(tm)" phenomenon which kills men in more ways than just suicide. Men also don't go to the doctor or confide in others for emotional support as much, instead opting to "man up" directly into a shorter lifespan than women.
Women egg men into this by overtly preferring brutish unexpressiveness as it's "more masculine", but at the end of the day it's mostly men bullying each other starting from birth when this code is violated. Men are expected to rarely, if ever, dip into their emotional support structure-- this makes it largely useless. You're just expected to deal with it, repress those emotions, and put on a brave face to carry on.
Aside from machismo and being discouraged from getting help from anyone, men are frequently burdened by the responsibility to provide for their family, which is considered their primary (only) purpose. If a man loses his job, it's an affront to his worth as a human being. This is why middle aged men frequently kill themselves when they lose their job or are having trouble paying off their house; they suffer deeply and largely silently for perceived failures of manhood. The suicidal want an escape from their suffering, and as I've said before, there's really no way for men to ease their suffering in an acceptable way. Drugs and whatever are helpful, but ultimately aren't enough.
