Nope that's shit advice. It's ok to accept you have a stutter it's OK to shrug off how other people treat you. It's not ok to believe you can't get better, to give up on trying. You got dreams you wanna be a seal, well you better start acting like one. There is a whole internet of information on how to beat this, you tell yourself you will still be depressed if you beat stuttering because you are scared to try and fail. Stop giving into fear only you are going to be able to defeat this no one is coming to save you, but you have a vast library of knowledge you can access figure out something that works for you.
