moving out at after i graduate

so i’m going into my senior year. i turn 18 in a few months but after graduation i plan to move out and rent an apartment with my boyfriend. who btw my parents don’t know about. my parents aren’t allowing me to get a job. so i’m going to get one when i turn 18 in october. i just have so many questions about life and sometimes i wish i had an older sister who i could talk to and help me out and all of that. if someone is interested in helping me out i would appreciate it a lot. or if any of you have advice about moving out when you’re young that would be greatly appreciated. i just want someone who’s been through a little life that could help me out and calm me down about life.

i also plan to go to community college and work part time next year if i have an apartment. so any advice on how to save and bills would help a lot!!
