Hear me out, there is nothing wrong with you or your life and you don’t need to fix anything. Start slowly, smalltalk to a neighbour or with a “Hey, how are you” to cashiers when you go shopping. Try to smile when you talk and always remember it’s okay to stutter. If you encounter a block, just tell “please bear with me” and never ever say sorry for stuttering. Eventually you will gain confidence, start talking to people at school or gym whom you feel share the same interest or hobbies. Wishing you all the best! I got 99 problems but stuttering ain’t one..
