Email financial aid and let them know that you undertook the work needed to get these scholarships because BC is not affordable without them.
You shouldn’t go over 5.5k in loans.
If the total gap between budget and direct costs that you and your family would be left to pay is higher than 5.5k, then you need to tell BC you regrettably can no longer attend because without the scholarships COA is unaffordable and will alas be using your scholarships at another college (typically these scholarships are portable).
You’d have to contact your second best choice that admitted you and is affordable, to see if they still have space for you with the same financial aid offer. There’s been a lot of turmoil in the past month so they very well could.
