Help, I think my college counsellor may have screwed me over

If your income dropped significantly, you could be eligible for a fee waiver as a US citizen - I think the threshold is something like 45k but you need to look it up yourself and hurry because there’s extra time to process the request and different deadlines, it may be a matter of days.

Next, are you Pell eligible and do you know your SAI? If you don’t know, check if you’re Pell grant eligible here:

It matters because Pell is an important marker for colleges.

Public universities won’t be affordable unless your parents are still official residents of that State.

You should focus on universities that meet need or close, where your scores would be fine or where you could be test optional (Gettysburg, Dickinson, St Lawrence, Skidmore, Muhlenberg, Macalester, Kenyon, Bates… All come to mind).
If you’re a girl, women’s colleges could be of interest. HBCUs also could be of interest to a history major, Howard with its setting in DC in particular (though you’d have to qualify for merit scholarships).
