I'm so fucking pissed and I feel like I shouldn't be okay so I'm staying with my mom she's married to my step dad and my blood Lil brother stays here too I moved back because of the help plus I don't have to work until after the baby and because I'm a Ftm I didnt want to be alone with an infant okay so since I've been here I basically been the only one cleaning which I'm fine with because I'm not paying rent or anything but I've been splitting the chore with bro plus I was helping my mom by trying to get him on a schedule because his ADHD he doesn't really know how to schedule heself but anyway evrytime it comes to his day to clean and all he has to do is clean the kitchen or do something on schedule he argues with me and if my mom gets involved she ends up doing it or making it easy for him now I've lived with them my whole life will my mom and brother until she married but as we grew up he had special treatnent as in he dont do shit but sit on his ass and I after I get the money to move I didn't want my mom being basically a slave because she doesn't work because she has a bad back but she already cooks and drops everyone off for work or school now I don't know if its because I'm a mom's girl or what but I thought that was a lot should I leave it alone and let her handle it with his schedule and I just clean by myself until I leave ? I think this was rant because I'm so pissed but im only concerned because I feel its lazy that he can't help around the house and when someone asks him to do something he always talks back but he can ask for something and get it right off the back like wtf sometime I feel like I'm being the parent maybe I should just leave it alone because I'm done with the attitude year this was a rant but y'all can give advice lol I'm just gonna mind my busy and clean myself smells better when i do it anyway 😊😊
