urgent advice needed

unsure if anybody will even read this but oh well i have nobody else to talk to about this

i’m y12 and struggling really bad with career choices and my a levels, i moved from a state grammar school in secondary to a private school (on the highest bursary) and i think it was a bad decision because everybody’s so certain with what they want to do but im just so stuck, everything i want to do (considering PPL or PPE) i can’t because of my poor gsces (everything seems to need a 6 in eng lang and i got a 5 even after resitting but an 8 in english lit my other gsces were 5-6s)

i got y12 ucas mocks back and did bad, i know BCC isn’t the worst u could get at all but everybody else has got minimum AAB even some A* so my teachers r treating me like im a failure, i mean they’re very lenient with ucas predictions so ill probably be predicted what my dream uni grades are, but i just have 0 confidence in myself and i hate my friend group and people in my school they’re all so arrogant and always trying to prove u wrong im so lonely

i also considered law but i just don’t know i talked to my teacher today which was a mistake i told her my a level combo and she laughed at me and said it wasnt that applicable to either im just so defeated at this rate i may as well just drop out of school altogether but my parents are immigrants and im the youngest child so i literally cannot do that does anyone have any advice
