I am under 16 i got into an minor two wheeler accident in my colony and my parents don't know

What Happened was i thought i am able to drive a two wheeler (Activa) i asked my friend if he could teach me how to i drive an activa and i did not told my parents about it and he said ok he told me how do i start it then he told me that drive it now and then i was able to drive it. and i did drove it a bit then a few hours later it was like 1 or 2 in the night and i was pretty excited and curious to drive it and that was my only chance to drive it beacuse it was my dads and i found the keys of it like two or three months before it i just kept it. so what happened was i started driving it and i was pretty well at driving it then like 20 or 30 minutes later my younger brother caught me driving it he was prety shocked (and he is under 10) so he caught me so ii got a bit scared cause he could tell my parents but i just told him. then i drove with him for like 20 30 minutes then the guard told me to go home so i did but then a few minutes later it was like 2 in the night and he told me that my dad teched him how to drive an activa and he told me that he said that i wont be able to drive it that's why i did not told you then my brother said that he could also drive at first he started saying to me that he could and he kept saying it so then i accepted it and went outside then he told me that sit behind me and just keep your legs down then he started putting full throttle so i stopped the activa using the brakes then i told him that dad will beat me if you get the activa hit to something then i went back home. then he started saying it again and again that i know how to drive an activa then we went again and he started giving throttle too much Again because a car was in front of us then he hitted the car i tried to stop it using brakes but it wouldn't because my brother wasn't leaving the throttle and he hitted an car on the back bumper and the activa did got into it a bit then he ran and went back home and acted like he cant breathe and he wants water but i could see he was acting but he was also worried and he just asked for water he did not drank it it was in front of him and he ran back home leaving the active there but i got the activa on stand and the steering was not moving it was moving just a little bit and then just a few moments later guard came he recorded me and the activa and the car and said i told you to go home why did you got back then i told him that my brother did it don't record me but he did then i went home and then i came back there and took the activa back where it was parked i got it back pretty hardly then my brother went to my mom and slept there and i am here in my room locked and writing this what should i do now and what can happened the worst with me and my family. please explain i am pretty scared.
