Thank you all for your responses! I’d like to say that I just sat down with my parents and had an actual conversation about aid, ED, and everything else.
It has been decided that I will ED to Duke. I did not fully grasp our financial situation, but my parents are in agreement that they will be able to handle the cost of Duke, even without the financial aid office considering our one-time income a special circumstance. We’ve worked out a plan, and it seems like it will be just fine. I’m going to graduate with student debt, but who doesn’t? It won’t be debilitating according to the net price calculators.
No need for more responses. I think I’ve finally eased my worries.
