There are good coping strategies and bad coping strategies. Many people claim to stutter less while on illegal drugs that can also cause addition - is this a good coping strategy or not? And these 'false hope' tricks set people up for a further self-esteem crash that can cause real damage, perhaps triggering all sorts of terrible behaviour. Hiding away is also not good coping strategy. There are plenty of techniques that have lasting effect, improve self-confidence and lead to a long term better quality of life. This person's 'advice' is the opposite of this.
