My daughter went through this too! It seemed like forever before she was done! I know how awful it can be. Please know that it will pass and soon she'll be her happy, sleepy self again! :-)
In the mean-time, get this MIRACLE natural remedy we found:
It's called Children's Teething Relief and you might be able to find it at health food stores (like Whole Foods) but my mother-in-law buys it by the case online... maybe even off of eBay. It is all-natural... like chamomile and other herbs. And our daughter, Emma loves it! When she sees the bottle, she says, "More?" and opens her mouth for us to give her drops.
It honestly is like liquid-gold in our house! Emma's teething was HORRIBLE the first time around, but after we found this, we hardly even notice until her new teeth are there!
Here's the website:
