Why is mental health important?

After having to lose my brother to suicide, i was diagnosed with PTSD, anxiety, and insomnia. Coping up to what my family had lost, was the hardest thing we ever had to do. Depression is often confused with sadness because of which, in today’s time, anything sad is replaced with depression and this kind of casualty has forced people, who are actually going through it, to hide it behind their smiling faces.
