I'm getting so pissed!

Every single bag I have looked at is too small! Why is this turning out to be so hard? I dragged my husband all over town today and we came up with nothing. Everything was just too small. Why is it so hard to find a messenger bag that's like 6-8 inches deep.

You'd think someone would make one.
I looked at the Case Logic bag... it says its 8 inches deep on the website, but there's no way that interior is actually that deep. Too much padding I guess. ::sigh:: I guess I'm going to school on Monday without my books, I can't carry all of those without a bag. Damn! I'm so stupid... all of my classes are one right after the other so I actually need to take all of my books with me.
