However, since you have a plant growing already...here's what I'd do to salvage it:

Get some CFLs (Compact Flourescent Lights) and put them close (only inches away) to your plant(s). Then set a timer to light the plant 18 hours on and 6 hours off. Then leave it like that for several weeks while you read up. If you are in soil, you should be ok to just leave it alone for a little.

Does that help?

Oh, and by the way, none of us are professionals either.
