Read the dozens of other threads on here about emancipation and you'll find your answer. Your answer is - no.
Emancipation is for those minors who are already living on their own. Not the ones who want to get away from their parents or who don't like their parents rules.
Good for you to make your own appointments. You're 17 - why couldn't you make your own appointments? Or pay for car insurance on the car you drive? That's not true that if you pay for your phone he can't take it away to punish you. I don't know where he got that idea - as long as you're a minor he can control your life.
Nothing you have stated would allow you to get emancipated.
Does your dad have custody or your mom?
If he's drinking on the job, report him. What would you do if your dad wasn't the manager? I sure as hell would report any supervisor who was intoxicated while at work.
His girlfriend "talking about" you - address it with your dad and if he won't do anything address it with his girlfriend.
You don't have to give him money. If he abuses you, report it. Why didn't you tell someone when he threatened you? Did you tell your mom? Does she know about his alcohol problem?
". My aunt, and both of my grandparents would let me live with them." This is completely not the point of emancipation. If you want to be emancipated you have to show a judge you are on your own already. Not that you want to live where you want to live.
This is how Mississippi views emancipation: "Under Mississippi law, when a minor requests emancipation, the court considers the child's residency status, age, establishment of independent living arrangements, the ability to provide financial support for his affairs and whether the parent or guardian provides consent." So your parents have to consent to it as well. It seems actually the age of majority in Mississippi is 21...although at 18 you can enter into contracts.
Bottomline - you're not getting emancipated. I would suggest you talk to your mom about her getting custody.
