Why the Sleep Pattern?

I find that when I go through something that causes my anxiety to raise to a very high proportion. Because of that, I got so worn out that I managed to sleep from about 8pm on friday to 5pm saturday. It's outrageous how sometimes my body has a habit of getting back at me since I've such in mental issues. I have a writer's block. I heart my sleep but I heart a job even more. I really hope that I mamage to get this job. I am so tired of being unemployed. I really need a job. I'm going nuts.
