I know exactly how you feel, i have been there so many times! There are not many hairdressers around that seem to "understand" what we talking about, though there are some fantastic hairdressers too.... but at one stage i was finding all the wrong ones! Now i have one person that i trust enough to give me a cut, but it took me years to find her.
Thank goodness it grow back, but i also know it doesnt make it better right now. It's horrible to be unhappy with your hair, after all, hair and clothes are the feathers of us woman huh... and we want it to look good, specially now with Christmas coming up.
Hang in there girl, in a few weeks time it will look and feel a whole lot different.
