being a 20yo already finishing hs i can speak from experience that it will not go away. idk how "bad" ur stutter is but for me its was had it days. but dont let that stop you from what you want to do in life. Make friends who accept you for who you are. find a significant other who doesnt care about your stutter but who you are as a person. if you have right moral in life your stutter isnt going to hold you back.
