I had the same issues with my last application--it was a rough couple of weeks between my 2nd to last and my last app, but somehow I slogged through it and kept reminding myself that I would be DONE so soon.
To top it off, I got a wicked bad cold 3 days before the last one was due AND had a mishap with my roommate's cat AND my computer laptop charger died. Oy. But I SURVIVED and I got an interview invite for my last app, so keep chugging along.
Then you get to join the rest of us in the "limbo" portion of the application process
