You are strong enough. I have found that if you could say to yourself in your head that its possible thats enough. In time you will feel like it. I actually beat my stutter. I am 20 years old stuttered ever since I can remember myself. It was before I was about to be reqruited to the army thtat my mind body and every part if me understood that Im tried of living this way, being a ghost in the world and not controling my own body. It was a year and half ago and the one thing I can tell you remaind ever since that day is me telling myself I can. Even when I literally couldnt I still forced myself to believe even when it was hopeless. I believee and kept repeating in my mind that I wont stutter. I learnee a lot and read so much about everything related to stuttering from manifestion to neurosicence but whole heartedly the one thing most important is your belief in yourself. Even if you have none right now. It is forged - as long as you are conscious you are capable of belief. It wont be easy it will suck but what other option do you have. Self loathing and depression? Your choice.
