What u/chlebaspascikou said is spot on here. Assuming you’re in high school, you’re already going through a ton, and then you’ve got a speech impediment on top of it. It’s good to talk to someone or at least find out what those anxieties are. I didn’t do that until college, and I really regret it. Talking to someone really could have alleviated a few things that happened late high school / early college to me. Speaking from experience, parents are, in their own way, trying to help. It might not seem like that, but my parents were the exact same way until after I graduated college. My dad used to lecture me on it everyday driving me to school. My relationships with them suffered because of it. But as my patience with them grew, so did their understanding of the problem. I can’t remember the last time they brought up my stutter, and I’m in my mid-30s now. I’d recommend doing some research and putting it in front of them. Prove to them that you’re not in control of this, and that certain stresses make it worse than others. And that them continually putting pressure on you about your speech (whether they realize it or not) doesn’t help. They’ve probably heard it before, but coming directly from you instead of a speech therapist or other third party, they’re probably more willing to listen and understand.
