I have suffered social anxiety all my life until a few years ago, to the point that I never even went out at night in my twenties.
The answer to improving mental health is looking into yourself, identifying your fears, and then exposing yourself to them little by little. In time you stop acting awkwardly in regards to your trigger whatever it may be, your looks, your weight, your hair color, your smile, your race, your social status, etc.

Thanks for your wise advice Jupiter, much appreciated!
