Beaser,
I'm sorry to hear that you're feeling like this. TonyWK has given some great resources, and it is good to think about how some people don't deserve our worry. You deserve the position just as much as anybody else going for it, and your hard work over the years is more than enough evidence of your dedication, commitment and work ethic. This is already a good trait to have in a new job.
I'm still fairly new to the workforce in the grand scheme of things, so I'm not sure if my advice holds a lot of weight here. Either way, I wish you the best of luck with your job endeavours.
SB
