Confused and afraid

Hey, im a 21(F), pursuing btech in cse, and for last two months i have been doing an internship in this bangalore based startup, all of there major shareholders also employees are out of india...... so the thing is, i started working in dec 2025, and i had no bg of react, the technology that they asked me to work on, and so i tried learning, they were also kind in the starting, but then gradually 3 more interns joined in, and since then it has been so much pressure from my TL (tech lead/ team lead) to always finish the work ASAP, and due to that i have taken a lot of the help from chat gpt to get my codes, understand the flow and everything, so now after 2 months, i do know things but not in a manner that i can do everything on my own...... problem is, since past few days, my TL has started talking so rudely and gets angry if i ask him anything related to work, so now i feel so scared from the thought of just work in itself, and when he talks rudely or angrily to me, i cant even shut him with my words, because im not that great and strong with my work/skills, to not feel scared and afraid but confident.

if you ask me, i dont give a damn about my TL anymore, i just want to not be scared or afraid of work at all, i just want to feel confident enough that i will handle the work no matter what anyone says.......... rn, at this point, i see work like this huge mountain in front of me, that im so scared of, that what if chat gpt doesnt works, what if my TL insults me and i cant answer him back, because im not that good at what im doing. please help me out with this, i dont wanna remain afraid all my life. please.
