Gabapentin's principal use in medicine has typically been as an anticonvulsant. However, studies undertaken in clinical settings over the last several years suggest that gabapentin may be useful as a mood stabilizer because of its ability to quiet neurons in the brain.

Anxiety and sadness may respond well to Gabapentin:

Gabapentin is sometimes used to treat mood disorders like depression and bipolar disorder because it protects nerve cells. Some evidence also shows that it helps with anxiety. Gabapentin was made to treat seizures at first. Clinical studies have shown that gabapentin may be just as good at treating generalized anxiety disorder as benzodiazepines.
