Before you can move out you need to consider several things.
- shelter
- food
- clothing
- money
The biggest question is how desperate you are to move out. I don't mean to sound callous, but this is as realistic as I can be. Now, you can move out. You can pack a bag with some belongings and leave.
1. Money - You can try to empty your bank account, but you would need to do so before they find out you are gone and take it all first. To get the money you will need to know which bank to go to, and you will need to bring identification. You may also try to bring the bank statement which should help them know which account is yours and that it is yours. But your name needs to be on it. If it is not in your name, you don't have access.
After you withdraw it you can go somewhere else (and I suggest going to a completely different bank) and open an account yourself. This will help to not be robbed. And if your parents were to find you, you don't have cash they can take.
Please note: Since your parents pay your phone bill, you may need to get a new contract as they will probably call and disconnect your phone service once they have found out you have left
2. Shelter - This is super important. You need somewhere to sleep and to keep your stuff. If you cannot stay with friends you can go to a domestic violence shelter or some other shelter. As much as this is not your stereotypical domestic violence, it still is. It's just your parents and not a husband or boyfriend who is doing it. They can probably help you find temporary housing. They are also able to help you find a job to build your resume or to send you to free job training classes to build your resume. You will most likely need ID for this. If at all possible, get your social security card and birth certificate. If your parents won't give them to you, you could fake having a job interview at a place they approve of and tell them you need to bring your social security and birth certificate. This isn't super unusual for a business to do. Or if you want to pretend to volunteer somewhere they approve of, if there are children there you would need a CORI check (if you are in the us) which would require you to bring those as well. If you cannot get ID before you leave, then it may take a little longer or involve a few more steps. But the government/hospital will have records of your birth certificate (hospital) and your social security card can probably be re-issued using your birth certificate just like if your house burned down or you lost it somewhere.
Clothing - That is kind of important, but should not be hard to obtain. A homeless shelter, or domestic violence shelter, or even a church or food pantry should be able to provide you will enough.
Food - Again, food pantries will be able to give you food and once you have the necc. ID's then you can apply for food stamps (again, US)
Lastly, I suggest you carefully (but secretly) plan this out before you do it. You can map out food pantries or shelter or get in touch with friends or whatever you need to do. But it's a big decision, so just make a plan and a back up plan and a worst case scenario plan.
If you can, you may want to bring expensive items you might have (jewelry, electronics, name brand stuff) to sell or pawn if you run out of money. Also, remember to pack anything sentimental so pretend like your house is going to burn down tomorrow and anything you don't take won't be salvaged.
If you are in a small town and/or your parents have a lot of power or know people who do you may consider going further away. Obviously this depends on your situation.
I really hope this does not seem harsh. And I am in no ways discouraging you from running away. You are a grown woman and you should not be kept captive, especially in an abusive and disrespectful environment.
I really hope this helps, and that you keep in touch if you need more help or just to tell us how you are.
