Introvert, social anxiety, or possible autism??

[incel1no]

i can only talk normally to my friends, the ones ive known since first grade. When im with them, i can talk normally, i can joke, talk shit and be myself. but the second i talk to someone else, my brain shuts off and i dont know what to say, at all.

when i was around 13 i randomly turned shy and lost the ability to talk to others, and since then i havent made any new friends. When someone talks to me, i overthink everything and i dont know what to say back, so i basically just stand there awkwardly thinking about what i should say, and end up saying nothing or just some dumb bullshit. I feel awkward all the time when im around people, im scared to say something weird or wrong. so i usually just stay quiet, even tho i dont want to.
Like in class, if the teacher asks me a question, no matter if i say the right or wrong answer, i can feel my face getting red, it feels like my face is on fire and my whole body gets hot as fuck.

and its just weird how this shit happens around others, but when im with my friends im the most talkative person there.
How do i deal with this?

Wild still being in touch with people from that long ago. I don't have contact with a single person from elementary school

autism starts at about 8 months old and is detected in kids most of the times up to 3 years old so if ur parents didn't notice nothing wrong like very late to start speaking or having problem with eye contact etc u are not autistic.
