It’s different for everyone. Some visually impaired people can wear glasses or contacts to correct their vision. Some are just unable to see. My stutter benefited from meditation. Breathing exercises. Subliminal suggestion (sort of). It also benefited from practice and just maturity as I grew up. I feel I am lucky in that regard. Some people aren’t as lucky and if they want a place to feel seen, vent their frustrations, feel vulnerable, who is anyone to come into this sub and criticize them?
