I totally feel for you and have been there/am right now there myself! Our dd didn't sprout a tooth until exactly eight months (had teething symptoms from about 8 weeks onward, it seemed - drooling, baaad drool stool episodes, crying,crying ,crying and nursing ALL night long, inflamed gums, etc..) and then in a month's time pushed out 6 teeth.
for me, the severe sleep deprivation was the worst- actually the day after a sleepless night is worse than the night that preceded it for me. My coping stratagies are to try to sleep with Amy during the day (even 30 minutes helps), keep my expectations for housework low, remember that this phase is transient and she will grow out of it, get support from other moms.. funny thing that my dh said last night that he feels so tired he can't really think well -- I said, "hello! that's how I feel pretty much most of the time!"
