Stuck in a loop and running out of time

Hi, I’m 17 and live in the Uk. My parents took me out of school a year and a half before my final exams for being a victim of bullying and Insisted on homeschooling. Ever since I have gotten addicted to video games and doing NOTHING. I am 18 in a few months and since this I have become overweight, gained pretty bad anxiety about the way I look and how people think, I have pretty bad adhd and so I can barely do ANYTHING. This being because of the adhd and video game addiction combining and I have been in this loop for nearly 4 years. Homeschooling never happened, my parents just forgot about it and me being a kid 3 years ago just was like “fuck yeah video game time” and ever since done nothing. In the past month or so my parents have told me to get a job and start thinking about moving out ect and I have 0 idea wtf to do because my stamina is at an all time low and my anxiety makes a job practically living hell. I need help cuz I’m starting to freak tf out 🙏🙏
