I would pray. Meanwhile I would think of getting a job outside academia. Look again at your applications, analyze them, why they went south, whether it's a problem with your application itself or a problem with yourself. To some, grad school is just a job. You could definitely find other jobs if you plan to. It's not the end of the world.
Congratulations to both of you and those who got admissions to wherever you had applied! Now is a really tough time for those who are still waiting for decisions and/or preparing for interviews like me. Just hang in there and don't lose hope.
Did you both apply to the WashU's BME phd program? I did but didn't get the email about checking status on 1/30. I did check it however it's still showing as "Submitted". I guess this can't be a good sign given that @sac830 has been accepted. btw, congratulations!
while most of my applications go to neuroscience programs, I applied to the bioengineering program at U Pittsburgh. Haven't heard anything from it yet. Trying not to lose hope nevertheless my other apps don't seem to go well
