Asking if ANYTHING is a valid reason for emancipation is a little like asking, "If I have a really nice apple, can I buy a banana and make a fruit salad?"

In the above example, it doesn't matter how many apples you have or how nice they are. You can't buy a banana, let alone make a fruit salad, unless you have the money to buy a banana. There's no point even going to the produce market unless you do; the grocer isn't going to give you a banana because you're going to make a fruit salad. Once you've shown the grocer that you have the money to buy the banana, THEN he might give you a fruit salad recipe with the banana. And of course, this all depends on whether or not there's a produce market nearby.

With emancipation, it doesn't matter how good or how bad your reason is. Unless you can show the grocer (judge) that you have the money to buy your banana (a history of and are capable of supporting and caring for yourself in all respects, including but not limited to being able to pay for your rent, food, clothes, utilities, medical care, transportation, insurance, and all the other needs of life), while going to school and getting good grades, there's no sense even going to the produce market (court). Only when you have shown the judge that you are financially capable of being on your own will he be willing to examine your apples (reasons) and, if they're sufficient, consider giving you a recipe for fruit salad (emancipate you).

Note that it will NOT be enough to say, "I'm going to live with my BFF/boy- or girlfriend/their family/a family friend/Aunt Susan/my grandmother/etc.". The judge will still not emancipate you unless you can show him that if/when the friend/family member gets tired of supporting you/gets hit by a bus/is transferred out of state and cannot/will not take you with them, you will still be able to support yourself entirely.

NOTHING is by itself a good enough reason for emancipation unless you can prove to a judge's satisfaction that you can buy that banana.

And, this all depends on whether or not there is a product market (law permitting a minor to be emancipated) in your state. Not all states will.
