Need some serious help with the future guys

Hi everyone. I applied to few universities for this years intake but got rejected everywhere, left hanging by two universities though. My stats- final year of high school grades were pretty mid 78% while junior high school grades are 95%. Csca scores are- 65 physics and 85 maths. ECAs were Olympiad winner, hackathons, took pre uni course and grades were 90%+. IDK where I lack but I applied late April- early May. I’m thinking taking A- levels this year since my 12th scores are low and I genuinely think I can get good grades since it’s easier than my curriculum. But like would they still look at my 12th scores? Idk I want something to outshine my 12th grades. Well I am aware that it will be my third gap year but I am thinking of doing an internship or work. I think having some work experience in gap year won’t harm my application. Give me some advices y’all. I am so lost, absolutely don’t know what to do. I feel like a disappointment and absolutely hate living my parents, it feels suffocating. I was looking at language programs earlier. Should I go for that but it is kinda expensive for me and I would need scholarships. Is there anything else I should look up to? I would be very grateful if u could help even a tiny bit. Thank you in advance.
