Banking issue with parents?

Ok so my parents have continuously been taking money out of my account without asking. its not for punishment or anything like that, they just don't want to spend their own money. So they figure if they take mine then it all works out. In total they probably owe me close to $7000. I'm really tired of them taking the money i make with my paycheck simply for their leisure activities. I have Midfirst banking and i was wondering if i would be able to separate my account from theirs. I know we have a joint account so they have full access to my money. I was wondering if i would be able to make mine into a singular account that only the bank and i would have access to. Is this possible?
