I'm fat and lazy, I'm tired of it.

I’m a 14-year-old girl, 5'1" and 156 lbs. I’m struggling with my health and habits, and I don’t want to keep living this way.
I feel extremely lazy and unhealthy. I keep telling myself I’ll fix it, but I never follow through. I keep eating mindlessly, playing video games all day, and scrolling on TikTok nonstop. I struggle to find the motivation to get up and exercise.

Both of my parents have diabetes—my mom has Type 1 and my dad has Type 2. I know that if I continue living the way I am now, I’m putting myself at serious risk. I want to change that. I want to become as healthy as possible, no matter how long it takes. I want to be the best version of myself before I graduate high school so that I enter the world as a strong person.

My current goal is to reach 130 lbs and build a healthier lifestyle overall.

Does anyone have tips? Anything at all. I would like to know any sort of thing that will help me gain motivation, confidence, overall my life.

Thank you for anything, from anyone.
