Hey I'm really sorry to hear that. It might just be me, but I think what you need are some answers now. Specifically, why all the rejections when it seems that you have done everything in your capacity to make yourself as attractive a candidate as possible. It probably won't work for your job applications, but have you considered calling up some of the grad schools and asking for the rejection reasons? Some won't give you a straight answer, but some might. I'll suggest calling the admissions chair/POIs directly and find out why. At the very least, if you choose to try again, you won't be searching your way in the dark, and you'll know how to improve your application profile. Remember, you can always try again!
