Many people have applied to the jobs they needed, or most dearly wanted. And as a result did not get it. The provided the most education, the most experience, and the most of everything! And they gave it their all. To see their job fly past them, and never hear from that company ever again! Has this happened to you well its happened to the best of us!
We either go out, or stay in, and apply to thousands of jobs, not one, but thousands. And never even get a word back from them, ever! Some might come back to say, sorry although your qualification(s) are impressive, but unfortunately we did not want to further you into the hiring process. It is a challenge mentally, as well as physically making us sick. By the time we get the job, we are so strung out we do not even know what the hell it is anymore!
Just remember its a rat race, people everywhere, hundreds of people are applying to the job that you want to get so badly. And not just that, you have to have a Resume that fits their own business system. I know it seems impossible, or even not worth trying anymore at any given point, apply to as many jobs, not just one but many. There are a lot of competitors, and you have something better than others skills set. Even if it is just a G.E.D., or High School Diploma, or nothing. Every company is trying to see if you can really do the job, and do it rightly.
There are to also people who have illnesses, disabilities, or physical pain. And they deserve a shot at work also. Everyone deserves to have a Job, and enjoy life!
