Interviewing Really Sucks

Out of my four-month long search, I was offered two interviews. I went to one, felt really good about it, and, of course, was not chosen for the position.
I thought that I did really well. I was so happy to have any chance at getting a job that I practiced, read online review tips, and tried really, really hard to make sure that I appeared professional. I took out my nose stud, put on subtle makeup, make sure that my hair was perfect, ironed my suit, and made sure that I wore closed-toe shoes. I brought a copy of my resume in an official-looking folio. I asked questions, made myself seem interested in the position, and tried selling my proofreading skills.
I still didn’t get it.
After this interview, an HR representative from a publishing company (publishing is my dream career) sent me an e-mail asking me for writing samples. I was so excited.
Nothing came out of that, either.
I’m really discouraged at this point. I’m tempted to go back to waitressing, just to occupy my time. I’m applying to jobs left and right, and it has gotten me nowhere. It’s so frustrating when my peers are all employed – even more frustrating when their parents or friends of their parents are the ones that have gotten them these offers. I don’t have connections like that, unfortunately. Doing the right things – like volunteering, getting internships, getting published – hasn’t done anythign for me. I don’t know what’s next for me, yet. I guess I could always throw myself into sales.
