The best way to help a person who may be going a mental downside, is how we respond to them. Sometimes people want to feel important rather than being told they are & we all should value the mental health of our friends, family or even strangers. It's very important that we see everyone through the same lens when it comes to mental health, anyone on earth can go through any form of depression or mental illness. Love the people around you and show compassion to the strangers you encounter.
