One fall doesn't define you or your ability to thrive. Yes, it hurts and it sucks, but just keep in mind that it's your attitude towards difficult moments what truly defines you. Accept the fall and keep going. Whatever happens, do not stop. Someone may have said no, but someone else may say yes tomorrow.
And btw, this isn't the first time I apply to grad school and I have already been rejected by one of the programs I applied to this year. Just keep the hope alive!
