Is what I did correct, in reviewing my wife after uttering a divorce in a fit of delusion, and is she still under my marital bond, especially since consummation did not occur, but merely a private meeting?

If you are not certain about uttering the divorce (talaq), then the divorce does not take effect, because the original state is the continuation of the marriage (nikah). If you are certain about the divorce, then your wife has returned to you by your taking her back (raj'a) during her waiting period (iddah), because a valid seclusion (khalwa sahiha) holds the same ruling as consummation (dukhul). It appears that you are suffering from obsessive whispers (waswas), so you must beware of them and seek treatment for them.
