OMG I'm ready to pull my hair out in total and utter frustration!

It's been a horrible few weeks/ months! I've been looking for a job since March, and applied to every single kind of job, from McDonalds to Walmart, to office jobs, to retail....
not one single interview!!!! Am I THAT unhirable?!?!?!! I tried temp agencies and still nothing.... I don't get it! So I'm keep applying, but there is only so many rejections you can get before you just have no confidence anymore in your own abilities...and that's where I'm at now.
DH has a job, but no flexability. We are supposed to go to Disney World for a Family Reunion in May of 2007, and DH asked for the time off, and now they are telling him that they won't be able to give him that time off...simply because they won't hire another Manager!!!

I told DH to look for another job, but there is nothing here! We can't afford to move either.
Then there is the car...it's completely paid off, and we got it last year. It's a 10 yr old car though. Anyway, it needs some work on it, but we don'thave the cash to pay for it, we don't have any credit cards, and we've applied for some, but since I'm not working, and DH has a crappy credit rating from before we got together, he gets rejected too...so basically once our car dies, we're even more screwed! It needs an alignment desperately, an oil change, and tune-up, none of which we can afford.
I HATE BEING AN ADULT!!!!!!!!!!!!!!!!!!!
