What can I do?

Hey guys. I (18F) am lazy. I quite literally do nothing all day except smoke weed, watch greys anatomy (ive watched 3.5 times and currently on my 4th watch), and doomscroll. I go to bed at like 1-2 am and wake up 1-3 pm (tbf I have a night job so I don’t get off until 10 pm but that’s no excuse for waking up at 1 if I’m going to bed at 1 😭). I haven’t graduated because I switched to a self paced online school for my mental health. I have a year left to do it and I only have the credits of a sophomore. I want to clean the house, work more (I barely work; like 2-3 days a week 4.5 hr shifts), save up for a car (I have less than $100 in my savings and I’ve been working since 14 🫠), I want to do the hobbies I like but I binge watch/read abt them on social media. I like doing yoga and exercising and eating healthy but then I get lazy and don’t do it. I’ll do one good habit for an hour everyday for a week and then stop doing it. I have a really hard time with the reality that my life is my life and i have to change something. I live through other people on socials/greys. My dopamine receptors are fried from smoking weed from 12-18, scrolling, planning but never doing, and constant stimulation. I am comfortable how I am but I always say I’m going to change and I’m gonna do better and just one habit at a time and all the positive shit and it doesn’t work bruh I’m fed tf up tbh. I don’t know what to do and I’m definitely overwhelming myself.

TLDR: I do literally nothing all day but have a lot of things I want to do but don’t do it
