I want to get divorced but my family isn't supporting me

I really can't take it anymore; I'm tired of the constant fighting and noise. But whenever I bring it up with my parents, they brush me off with things like "it's not easy to build a home, be patient". I genuinely feel very alone and helpless. I want to get a divorce and go my own way, but honestly, I currently lack the financial means to do so. I'm at a loss about what to do.
