What year are you in now? And what’s your state of residency?
Keep in mind that one thing your independent status confers is the ability to establish residency in any state, irrespective of where your parents live. So, if you’re really hitting a financial wall at GWU, you could move some place with a strong public flagship and good state-level financial aid, work for a year (both to save money and to establish residency - can attend community college if you aren’t already done with lower-division coursework), and then transfer to that flagship with in-state status.
If you can transfer to a tippy-top private with generous aid, that’s the ideal outcome, but a lot of those schools take very few transfers so it’s good to have a Plan B that is also solid.
