Feeling completely lost. Anyone else from the 2081 batch stuck after failing Class 12 for the third time?

Hey everyone, I just really need to get this off my chest because the loneliness and guilt are eating me alive right now.
I'm from the 2081 batch, and I just found out that I failed my Class 12 re-exam. This was my third attempt at trying to clear this stubborn paper, and I missed it again. I am completely stuck in a loop while it feels like the rest of my friends and the whole world are moving forward, going to college, or planning their futures.
To make things a hundred times worse, my dad has a really bad, dangerous temper. Out of pure fear and survival mode, I lied to him and told him that I passed. I couldn't face his anger in the moment, but now l am living with a ticking time bomb. The anxiety of him finding out the truth is keeping me up every single night, and I feel trapped in my own house.
I feel like a complete failure sitting at home while time just slips away. Is there anyone else here who has gone through this? Anyone else from the 2081 batch or older who failed three or more times and felt completely hopeless? How did you deal with the family pressure, and how did you find the mental strength to keep going? I just really need to know I'm not the only one fighting this mountain. Thanks for listening.
