Failed attempt

I had this grat job interview, they told me i was what they were looking for and theyd get back to me. My friend told me one of her friends had the same interview same place. Its been a week since and I asked her how his went. She tolld me he already got the job and started yesterday. That really crushed me. I feel like shit, i need that job, how am i going to afford university at the end of the year? I have handed out over 50 resumes and no call backs. Im so frustrated and i feel very depressed, why do i even try, how come they didnt like me? whats wrong with me? this cements my feeling of having an empty future. How can i become something great if i cant even get a job where they told me i was perfect and a part time one at that? I cant handle this rejection, i wish i could just bury my face in my bed and never wake up again. Guess this sets back my progress for attending university.
