Man... Such a sad post. Been there, had those thoughts. Everything will be good, things will change for the better. Keep grinding and keep speaking. You are probably quite young. People with speech impediments can be succesful, just as everyone else. As a 33 year old I'm a team leader in a quite huge corporation, almost 10 years of marriage and 2 daughters. Workout like a madman, listen to some podcast. Things will change for the better. Don't give up, stuttering doesn't define you
