Am really stressed out now as well. I do have an offer, but had an interview at my dream-school about 10 days ago, and I haven't heard yet, though they said I would hear in a week or two. It could be any time now!
What makes it even more stressful is that this school apparently interviews a lot more people than they will offer places, so I really do fear I am rejected.
The chance, albeit a small one, of an admit keeps me sane. Thus though the waiting is freaking me out, it is better, way better, than a sure reject. How empty that would be.
Anyway, back to stressing and hoping...
