I can't function anymore and I'm so tired

I'm addicted to dokmscrolling and it's all I do everyday, 24/7. The shame is killing me. I don't do chores anymore, I'm depressed, my room is a mess, I've quit job searching and bettering my life in anyway. I'm just stuck in this hell hole. Sometimes I wonder hoe it was possible for me to be so functional and (somewhat) happy as a child. I was very much an overachiever but now I'm just a loser. No one else in my (big) family struggles with this so why only me? Sometimes I feel cursed. I want to do so much and be productive and present but I can't. I was supposed to clean 30 minutes ago but I just sat in place and now I'm lying down instead of cleaning like I meant to. I eat once a day at 10 pm because I can't be bothered to cook for myself out of laziness. My brain is genuinely fried and the only thing that brings me any ounce of happiness and dopamine is daydreaming and avoidance. I'm so depressed and when I'm living my everyday life I struggle with basically everything. I just feel like giving up, I'm so sick and tired of living like this. I'm barely even living and I feel like I'm just existing like a zombie
