My stutter is starting to take over my life. Is there a way to overcome it. Here is my story. Hi I am 18 years old and I have been stuttering since i was around 11. Until I was around 15 I never really stuttered severely and it was never a problem for me mentally. I was happy. When I graduated from high school I left my hometown to go and live with my dad In london, It was a big change for me and I found myself worrying about my stutter a lot more. After a few months it diddnt work out for me and I moved to the Netherlands to go and live with my grandparents, I also couldn't settle there either. This is when my stutter got worse. I found myself thinking about it every time I open my mouth and it started to take over my life. I diddnt feel free anymore and I started feeling depressed. Maybe because I'm unsettled and I think about my stutter way to much? When I meet new people or speak to friends or family who dont know I stutter, I can hide it most of the time and they wont notice I stutter. It wont be on my mind. But that is because I speak very fast to get the words out alot of the time. However when i speak to people who know I stutter ie. my parents, grandparents, I find my self constantly thinking about my stutter and testing myself when I speak. For example when I am speaking to my dad and I will stutter in a sentence, I was instantly lock off and feel horrible just because I tested myself not to stutter. I will also see there anxiety when I speak to them which gives me more anxiety and I will fully lock off. I am starting to feel severely depressed. Every single hour of the day there is not a moment I dont think about my stutter. It gives me anxiety about my future life. I don't know what to do anymore. I'm starting to give up. Some advise would mean the world to me if you could give me some :) thank you for reading.
