We understand your pain. I myself had the same problem for the last 2 years. Whenever I would muster up some course to speak for moments to anybody, that would become the highlight of my day. I craved talking to people but I couldn't. I started making video journals daily about my feelings and other things. This actually helped as I was finally speaking for atleast 15 minutes everyday to myself. This hasn't helped reduce my stutter, but I am happy I can speak something. I think you shouldn't give up yet and think that this will be the norm throughout your life. Teenage brain is very neuroplastic and can easily change if you try hard enough. I know you don't want any advice but I would just ask you to be optimistic. I assure that things will definitely change for the better.
