I'm going to assume that your parents still claim you as a dependent on their tax return therefore the emancipation ????
Mine did that too and it killed my taxes every year (I worked full time while in school) Plus no financial aid for me, parents made too much $$$. Tell your parents to stop claiming you. I think after a year of no longer being a dependent, you can file for financial aid with your income.
Now, if it's because you're parents drive you nuts, I suggest you move out. Once you're 18, you are free to go

(that's the parent in me talking! Could you hear it

)
As for the stalker, that's weird. Be careful. Someone who is obsessed enough to buy a ring with the hopes you might say yes (based on no factual experiences or reality) is walking a fine line between sane and insane. Women are attacked, harassed, mamed and even murdered by these types daily. Good luck!
