Why don't you want to live in this world anymore? Is it because you stutter? If yes always think that there's people that have it worse than you. People who can't walk, can't see, can't hear, can't afford food, people stuck in wars. I get it stuttering sucks I stutter too but don't let it stop you from having a good life. You may feel alone but I recommend that you talk to people like your family and friends. If you don't want to talk to them right now you could always join this subreddits discord and talk to people there. You're not alone
