Please tell Me there's a way to reverse Sculptra...?

The effects of Sculptra cannot generally be reversed. Other fillers can usually be used to fix what you do not like from the Sculptra treatment. I suggest visiting your injector, or a new one if you are unhappy with their service, in order to get a personal evaluation. 

I am certain something can be done to help you, but from your description it is difficult to know with certainty the best approach. Hollows can be improved with fillers such as Restylane and Beletero, and for shadows from a prominent infraorbital roll, Botox can be very helpful. Fine lines improve slowly with topical retinoids, growth factors such as TGF-beta, radiofrequency treatments or resurfacing procedures.  A consultation and careful examination with a dermatologist or plastic surgeon skilled in eyelid rejuvenation and a discussion of your options is in order.

There is really not a way to reverse Sculptra.  You would need to be examined or pictures of you would be needed to determine what your options might be to improve the issue under your eyes.  I do not recommend using Sculptra under the eyes, as it can cause visible bumps there at times.  It is possible that a hyaluronic acid filler, like Restylane, could be used under your eyes to improve the appearance.
