So thankful for everything my mom has done for me

including letting me live home well into my 20's while the rental market is beyond comprehension (i do pay some rent though, and lend her money any chance i get) but i just got into a huge fucking fight with her over her cigarette smoking. My mom and dad smoke a pack a day (almost each). I come home at 10pm every night after a grueling day in customer service full time greeted with my unemployed mom and the smell of actual fucking death from the smoke throughout the entire house. Everything wreaks, my clothes, me. Even our fucking pets wreak. I leave to go hangout with my friends and they smell cigs. I go to work smelling like cigs. I come home smelling cigs. I tell my mom so when are you going to start easing off those things. She says i don't know. I said well have you even tried? (we've been talking about it for awhile) (and I've eased off vaping and in the works to quit for good) she says no. This leads to a huge fight. She tells me my vaping is worse for me. I said you and i both know that is not true but it actually doesn't matter. You've been smoking your whole life. She says "can I just have one evening without fucking bullshit for once?!" (SHE SITS HOME, EVERY DAY, ON TIKTOK. ME AND MY DAD ARE WORKING MORE THAN FULL TIME) I've never met such a person with absolutely no fight in them. I went from drinking 4 days a week to once a month sometimes way less. I've successfully went a month without vaping. I've completely quit weed for 2 years now. I've pulled myself out of the darkest depressions of my life and still shown up to work no matter how shitty the job and pay was. I attempted different schools to aim for different careers. I've fought and won against severe back problems as a kid. I've worked myself to death just to save up for a car and did so in the matter of like 3 months. My moms health is deteriorating faster than ever and all she can do is "maybe I'll try maybe sometime eventually" but I'm the spoiled brat and that bad son for pointing out that maybe I don't want to walk through the front door and have my nose instantly burn for once.
