I'm the same age and I understand the comments, side comments and snarky things people say especially in school however its ur choice to actually acknowledge the comments or insults. Because I guarantee they don't after ten minute. So why should you? Having a stutter sucks but at the end of the day, its something even doctors and scientists haven't figured out why it happens, theres no cure, no way for it to go away. And at first its upsetting but you just gotta learn to embrace it i guess, it wont leave and there are days where I want to just normal but being normal sucks ballss. Go outside, socialise and no matter how scary it is. Its not. Find people you relate you and if their real, they wont care about ur stutter. Fight the anxiety, because truthfully you've got one life. Trust me when I say going out and finding people, is though difficult at first is the best thing for your stutter. It wont go away, but you'll learn to live with it more. Don't acknowledge the people being rude in your life, even if it's parents. With the school thing, research about online schools. Find jobs willing to pay willing to pay kids, local cafe's, corner shops that type of thing. Do your research and if you don't come up with something for now, look for the future. I know its easier said than done but even if you don't find anything at least than you've tried!
