My story and asking for advice and tips please

My story and asking for advice and tips please Im 16, male, and for as long as i can remember i have been stuttering. In elementary school i would go go a speech therapist but then they said im fine and didnt need to go anymore. Middle school was very rough for me. I was put in a theater class and had to undergo shows and performances and ensemble read alouds. It was the worst. I couldn't get the words out. My peers laughing. The teacher would tell me everythings okay but did nothing to show that. During speeches in school i would allways try to find a way to get out of doing them, for example emailing a teacher asking if i could make a video about the subject instead so i had to do less talking in front of peers. Sometimes the teachers would say yes sometimes no. It was rough. I remember thinking back , how many times i failed. Failed at doing such a simple task : talking. Sometimes it goes away and i can talk and ramble for hours, and sometimes i get locked and cant even tell the fast food guy my freakin order. I hate this so much. Im finishing my second year of highschool. Im quiet glad theres no school due to covid. Ive lost 90% of my friends, they simply dont care about me anymore and sometimes they even used to laugh when im presenting. For example in February i had a group presentation, there was a new kid in my group who didnt believe i couldnt talk right since when talking casually im usually fine ( depends who im talking to, of its to a girl or something serious to my parents its badd but most of the time it goes well casually talking) And he gave me this big chunk of stuff to say and i stuttered my way though it. He laughed while i was trying to say what he told me to say. The whole class was laughing. Maybe even the teacher. Anyways, im trying to get a job but its not so easy and im afraid that during the interview ill mess up. I have been trying to plan my next couple years out and im just not sure how im gonna do it with not being able to talk in tense and important situations. Ive been praying and planing but this big mountain ahead of me will be hard to conquer... and sometimes i wonder if it can be conquered at all or if i will have to adapt to it. Im fairly used to my peers laughing at me, but its still so difficult sometimes. Just had to read something 30 minutes ago on a zoom call. I did terrible. I know this is something noone understands but me. My dad tries to comfort me but it just kills me sometimes that i cant do such a simple task sometimes: talk. Thanks for reading. Tips would be appreciated Tldr: 16m, lost all my friends, been laughed at by my peers a bunch in school, how will i able to live a life like this? It gets bad when i have to present or talk about some thing serious or important. Tips welcome thank you
