achieve for being comfortable with yourself and not confident. i know it might not sound very helpful but when i embraced myself for who i was/am and not by some projections i wanted or thought i had to be .. i got comfortable with myself and got surrounded with like minded people instead of trying to be friends with others who i had to keep an image of who i wasn't. i went from stuttering a lot to being fluent. i speak english fluently, and i struggle more with spanish and italian (i learned all 3 languages as a kid and stuttering) as i don't practice them often. but this year has been very difficult and i noticed my stuttering coming back in english where i thought i was out of the woods. and this is definitely influenced because im not in a good situation, mentally, financially, and overall life. it's a confidence thing yes, but definitely just try to be comfortable with who you are. i crack jokes when i start to stutter to break the ice and that helps me overcome those situations in which you notice people looking weird at you or helping you finish your sentences.
