Why do Filipinos generally stigmatise mental health?

Observing from my own personal experience growing up in a Western country I've seen the many differences in the way that Filipinos generally approach (or in most cases avoid) the topic of mental health. My mum grew up in the Philippines and told me how that no one really talked about or wanted to be associated with stuff like depression in her day so I was wondering, why the stigma? And also whether that might be the case in Philippines today.
