PLEASE HELP ME !!! 😭😭😭

After completing 10th with avg percentage I started my preparation for JEE {just because almost all my friends began preparing also} with no motivation and reason. I got myself enrolled in an expensive coaching

Now nearly a year has passed and my 11th is about to end. This is my situation

1. Wasted my entire 11th [I don't know anything, ANYTHING]
2. My social media addiction is TOO STRONG (main reason)
3. Keeping my family in delusion by getting great rank in tests BY CHEATING
4. I don't want to pursue JEE and have no motivation to get into IIT or even ENGINEERING
5. Feeling suicidal and depressed all the time
6. Used to be confident but now I don't even have the guts to talk to my parents let alone teachers

BTW my father has already paid for my coaching for 12th
My family is very caring and supportive of any career [I insisted on pursuing JEE under peer pressure, but now I regret it]
I feel like my parents don't deserve me
My weekly avg screentime is 12 HOURS [FEELING VERY GUILTY AND WANTS TO KMS]

WHAT SHOULD I DO NOW???? I AM CONFUSED. PLEASE HELP ME!!
