How do y’all get your parents to let you go out 😠

I’m always stuck at home. I barely have any friends because I don’t go out much. I’m 18 & it’s easy to say “just move out” but it’s not as easy when you barely make enough money & trying to earn for college. My best friend invited me to the mall, just to hang around, I asked my mom & she said “no & quit asking, you’re acting like a child”

Am I supposed to just leave without asking for permission then 😑
