What I'll suggest is depending on how severe your stutter is I would remove that from the resume. It's not something that I believe should be there. Everybody has some kind of flaw and it's not like if I was crossed-eyed I would put that in my resume or application. But hey, listen. You are 18 years old. You are still young and have so many opportunities and time. I've been at your age and I remember that not having job or failing to get jobs got me concerned as well. But I can assure you that it's nothing to be worried about. You should continue school in my opinion. It's an opportunity to get out this situation you are currently in and I don't want hear you say it won't work when you read this, because it will. You have all the people around you to help you. Friends and family. Even people at schools. But what's important is that you talk to people and ask for help if you need it. You say nobody wants to hire you. I have the same feeling but I soon realized that I was both young and without a university degree. Which is why my applies for jobs get overlooked. Please take your time in life and don't let your problems get to your head. Reach out and talk about it. Ask for for help.
