Is this a good enough argument for the way my parents treat me?

my parents treat me like i'm still in elementary school... i'm 17 yrs old almost 18... my step mom makes me pack lunch every morning. dad watches for my bus, then walks me to the end of my drive way (which is a normal length drive way) bcs for some reason he feels i can't walk my self...?? it's not that i'm not appreciative for the things they do, it's just making me lazy. it's to the point now where i almost can't function with them... like i'm not learning to be an adult bcs they feel they have to do everything for me or with me... when i lived at my moms last yr, making me pack lunch & watching for my bus & walking me to the end of the drive way was NOT an option & that made me feel independent.. & i like that feeling. i HATE the feeling of having to depend on someone else.
