While you are waiting to hear back. Have you considered looking into schools accepting second round (late) applications. Many schools such as Washington State University and North Dakota State University will post graduate student positions they haven't been able to fill to APA message boards and on their websites. These are often good positions with funding that did not meet the right applicant, specifically someone interested in the PI's research area, during the first round of applications. If you are broke from your previous applications, I would still contact the PI you are interested in and ask for an application fee waiver. Sometimes they will find a way to help you if you seem like a good enough fit.
Best of luck going forward!
