I have performed really bad in my exams and feeling like i have ruined my life

I am almost 18M (gen category), in class 12th(pcm+cs), my last board exam is on 25 (C.S.). So i have messed up in phy chem and maths, if i pass my score would be like 50 in phy, and 50-55 in maths, 65-70 in chem, 90+ in eng and cs. I lost all my interests in academics this year, or maybe i was too much distracted and brainrotted by these instagram reels. Overall my %age would be 70-74, but less than 60 in pcm. I dont have much idea about career options, i cant clear jee(not even eligible). So basically i dont have any idea what i am going to do with my life, no career plans, low grades so i dont know if i will be getting any decent college. So i am feeling like i have destroyed my life, and also i dont have any other skills. So i need some help, suggest me some career plans. And also i come from a middle class family!
