Oh no {very bad word}...excuse me, Mr. Blogger?

I was trying to add something new to my sidebar {an almost daily obsession lately}, and well I hit something....some random key and I don't know what happened.
*poof* my template's gone
um...like... *nightmare*
I could commit hari kari just about now. It was there last night, but this morning....blank. My screen was blank. My template was BLANK. My screen was BLANK. I HAD NO MORE TEMPLATE. This will take a while....especially leaving for CHA. Sorry guys.
