You're 14 so you're probably in high school or middle school? Schools should have a SLP (speech language pathologist) which won't cost anymoney, caus its through the school. The SLP can help you speak fluently and also educate your teachers as well. Talk to your dad and/or a trusted teacher to meet with the school SLP so he/she can develop a clinical plan for you. All the kids that mocked me either didnt finish high school or didn't get into their top choice school. Focus on school and try to enjoy high school! Talking about how you overcame your stutter is great writing material for college apps.
