It’s better to look forwards than dwell on the past. This is why its so important to not have downregulated GABA receptors. Too little GABA in the prefrontal cortex has been implicated in PTSD, looping thoughts and rumination. Also it messes up your sleep. Too little GABA, too much REM sleep, too many bad dreams. You can't buy your way out of a loony bin tho. Anywho.
