I'm currently in my worst phase. Nobody can ever imagine. I need an urgent help🙏🏻🙏🏻

Hello everyone, I'm (19 M), currently in my worst phase of my life, . so this all started in Jan 2024, which was the start of my worst phase. I study at a 2nd tier college in India, pursuing BTech. I came back after my holidays from my hometown to my college to start the new semester, but suddenly I started skipping classes and ordering foods from my cafeteria, eating all the junk foods, spending nearly 1000 rs every day (I'm not from a rich family, just a middle-class family). I know that it will harm my health and my academics, but I was just in a flow, ki jo hoga dekha jaayeega aaj enjoy karo. I was not indulged in drugs, cigarettes, or even alcohol, and I've hardly h 0 friends. I literally spent nearly 20 days in my room ordering food from outside, lying to my parents that yes, I'm attending college; suddenly, on one random day (after 20 days), my father messaged me at 12:30 pm, just when my class ends; he usually messages/calls me around 3/4. Then I called him to know what happened. He then tells me, Kitne din se class nahi jaa rahe ho? At THIS MOMENT, I understand what I did in these entire 20 days. I cried and told him everything; my parents also cried that day, and I understood what I had done to my life. FAST FORWARDING to MAY during my end-year exam, when I was not able to get the able to sit in all exams due to low attendnce, which led to get me getting back in 5 subjects an a year back. Now I've got to go to the college in January. I've gained 20 kgs during this time, and I'm now 80 kgs. I'm ugly, not in any position, neither in academics nor in the physical phase. I've become a burden on my parents in these 6 months as I had to stay in my hometown. Please tell me, guys, how can I make a comeback? I want this to be my best year. Please don't suggest leaving the college; I have to show everyone that I can fckinn make a dream comeback. Please 🙏🏻. Thanks for taking your precious time in reading this.
