i dunno...we all have our down days. you could just be human (not yet a diagnosis in the dsm...). haldol can cause or exacerbate low mood, depression, induce dypshoria, etc. i mean, I think --any-- major tranquilizer can, but haldol is known for causing dysphoria and general low mood, plus all the eps and td, etc. ((not trying to be a bummer bob, btw...)).

antidepressants sometimes make depression worse and can cause depression when used for anxiety, ocd, etc. lowering lamictal seems like it might open up some emotional flood gates and shake things up for a minute (I dropped my lamictal...after a while, my mood was better, but for a while there, things dipped...).

I hope things get better in your world. :-)
