Stressed out

I wanna go to sleep, but there are unfinished business on my mind. Do you know how to write a letter of interest? I guess it's very important when applying for a government job. Maybe I should re-write my letter of interest for that state job I've been drooling for?
Will they accept my revised letter?
How about the Pierce county job I applied today, it's in Tacoma. I heard Tacoma is not a very safe place and it's over-congested, too. Where should I go, I want a place that's nice, inexpensive, with lots of great outdoor. Olympia seems ideal, but there aren't many jobs there. So I want to get a job at the government.
Maybe I should start praying? like my devoted Christian friend suggested?
