It sounds like she overprocessed you in several areas. Once hair has been relaxed to the point where it loses its curl, it cannot be restored. It can only be grown out and the process be repeated. If she had underprocessed you, you could probably spend the next few weeks deep conditioning your hair and attempt a corrective to further loosen your curl pattern shortly thereafter. Unfortunately, it sounds like you'll have to grow it out and re-texturize again.
I texturize my hair myself. I am new at it and still getting a feel for how to properly process it to get the desired result. So far, I seem to have retained much of my natural texture. I am wanting to loosen it up some more, so I might be attempting another corrective soon - or switching to a stronger formula - or just leaving it on longer - or maybe using the same product but smoothing it more aggressively.
Virtuasis, Modelchick and a few others on here are very well-versed on texturizing. Hopefully, one of them will chime in.
