Don't kill yourself! As others have said, stuttering is just 1 small piece of you, I know you are so much more. It's not easy living with stuttering but you can find ways to cope and deal with it. It's a challenge and always will be, but good golly there is so much to life that you can enjoy and excel at. It's not always about finding the confidence or just accepting it (from my experience people who say that don't really get it), but learning how you are comfortable coping with things. Life is hard and stuttering unfortunately makes it harder, but there are absolutely ways for you to live it to the fullest.
