dude if you look back at my job apply posts back a year or so ago. I applied to over 900 jobs and only got 20 or so interviews. I got a total of 3 offers and this was right after the global financial meltdown. I made it into finance worked as an analyst and now i'm an account manager. Don't give up, never stop trying, adapt, and improve.
I've recently been job hunting as well along with working on my business. I've been taking my time as i still have a job and am waiting for my bonus but i've sent out over 100 emails since september and applied to over 20 jobs since then. Haven't landed one interview. I did land an offer last April right around my birthday but i declined it to go to Hong Kong and work there for a few weeks. Keep on trucking.
