Are my parents WAY too overprotective and strict? PLEASE HELP!!!!!?

[Gabby]

I can't take it anymore! I'm 18, but my parents treat me like I'm eight!! I'm a responsible girl, get great grades. But they're still too overprotective!! I wanna leave, and I have a part time job, but it's not enough to live on my own.

- They NEVER allow me to socialize. If I meet someone, I can't hang out. They want me at home all the time! I can't date (been asked three times), and I practically ripped their arm off to get my part time job. I've only ever had three friends in my lifetime (sad but God knows it's true), and my parents ripped them from my life.

- My dad works at home, and I've been "forced" to help his business for the past ten years. He wants me at home always so I can help him with filing and cleaning his office. His office doesn't need cleaned 24/7!!

- No social media, can't have a smartphone either because my dad thinks it's evil and that the Illuminati spy on us through them. He uses email. . . don't ya think the secret societies could spy on us using email if they wanted to? Oh, and I'm not allowed to have email because he doesn't trust me....Can't have texting on my STUPID flip phone. I've offered to PAY for a smartphone, but no..

- My mother has cancer, so I've been schooling my siblings (4) for two years. I help SO much, and they still don't let me have "me time" or any FREEDOM!!

- Can't wear makeup, can't wear shirts that go an inch below the neckline. My hair HAS to be past my chest.

What should I do? Thanks for your input
