people who left home really late?

please please tell me i'm not the only one. i'm 21 and i've never lived anywhere else but my one house and the psych ward. i genuinely cannot conceive of living somewhere away from my parents, staying the night somewhere is one thing but i can't not live in my house, im so scared. i'm so scared

i don't have the resources to leave unless it's absolutely necessary/physically unsafe for me to be here, i don't have my own car or anything like that. i'm just trying to get through school right now but that's the only thing im doing independently

did anyone else leave home at my age or later? i'm scared im faking because im staying with my parents longer than ive heard others have, im scared its "not that bad" because i didnt leave and cut contact immediately when i turned 18. im so bad with money and i dont know anything about the real world

this post will most likely be deleted soon by me just in case
