I cannot understand why

Life can be hard. Life can be cruel. Illness can take up a lot, but I can not understand why someone who has so many people who love & care about them will not reach out and ask for help. Mental illness is not seen as it was 20 years, even 10 years ago. I do not understand the stigma behind mental illness and someones complete disregard for life, especially when they have so much to live for.
