Please Help!

Forgive me for posting this here, but I am in a panic. (mods, pleasepleaseplease don't delete this until after I've gotten a chance to get some help!!) Somehow I clicked off the tool options for the main GIMP window and I can't even change brush sizes, or toggle the blur/sharpen teardrop tool, etc. I can't even work because I can't figure out how to get the setting back on!

I've included a screencap of how it is now, the way it is NOT supposed to look. That big blank area towards the bottom is supposed to have options in it.

Does anyone know how I can fix this? If so I would be eternally obliged!!
