I've also had 3 rejections so far (Brandeis accepted me for a Masters but rejected me for PhD) and am only waiting for BU so I'm in a very similar situation.
I'm actually already in a DMA at BU program (that is not funded, except a quarter tuition scholarship) so if I don't get in anywhere I will try and find funding for my current program, I think!
I think if I were you I would just take a year off and apply again for next year - I might also try and reapply for other places in the future. Good luck!
