I really need help with this.

I really need help with this. (14m) btw Right so basically I started having a bad stutter the other day with just like little stumbles and what not before that day (couldn't be classed as stuttering in anyway). But then someone pointed it out and then that night I kinda just spiralled and found speaking that hard i could barely speak altogether. And because it was so sudden I feel like I'm faking it to the point where I make sure no one is around me and I try to speak normally (it fails btw) I still end up stuttering. It fluctuates between severity a lot but there's a baseline that it doesn't seem to get better than. Please can someone give me advice I'm scared it's permanent and I'm confused.
