Im a 16 year old underweight kid with OCD failing every class in high school and getting 4 hours of sleep a day. I haven’t ate in 3 days and I feel like absolute trash. I wish one day I could have a healthy and happy life like everyone else. I am very desperate to change but it just feels impossible. Where do I start? What can I do? Any tips? Thank you for reading this, any help will mean everything to me.
