Am I worth it?

So, I've been rejected from a couple of places I applied. It really shouldn't matter because that happens to everyone, right? Well, it makes me feel pretty bad about myself. My self-esteem and self-confidence just went down a little more, just when I thought it couldn't get much worse. I don't think people realize how miserable I am. They say to change this and that and blah blah blah, but they don't understand that I can't. I know what needs to be done, I can tell you what needs to be done. I just can't do it. I can't describe it, but people, please stop. It makes things worse. It really does. I see a ton of people who are at the point in their life where I would like to be, but I'm no where near it. Honestly, I feel like the biggest loser on Earth.
