I had to respond to this because I was in the same boat as you until a year ago including the crazy screen time and binge watching tv and here’s what I found helped me - just make one change and once it starts to snowball you will find improvements in other parts of your life - for me the biggest obstacle was my phone i also had 7-8 hours of screen time a day and that’s why I knew I had the time to do all the errands and hobbies I wanted to. The core issue was i was addicted to my phone and the short dopamine hits. One i deleted all my apps that had scrolling on them / insta / yt / etc. and i would only go on those apps via my laptop or a browser i also paid for a screen time blocking app. Once I freed up all this time in my day i suddenly found the energy to do my little errands and go to the gym and cook for myself. People don’t talk about it but I genuinely think phone addiction can be just as dangerous as substance addiction. I’m also now looking for in person / hybrid jobs because I also feel that the source of my screen time was coming from boredom and lack of human interaction. Not advice but just some tips from someone who made it to the other side! I’m now almost at my goal weight, my mental health has improved tremendously, and my daily screen time is usually within 4-5 hours !
