moving out at 18

I will turn 18 in 6m & I am a Jr in hs. I feel very restricted by my parents to do anything including having a job bc I have younger sibling to look after while they work.

I have always wants to be independent and although I understand other people have a more difficultly situation, I think many can relate.

There are some things working against me:

-younger siblings

-no job thus no saving

-I want to go to college (not sure how hard it is to handle financial responsibilities)

-I don’t have friends or anyone who would be roomies

Are there any tips or advice that could be offered to me? I’m the oldest making my life have not much guidance or coordination.
