I experience "agitated depression" as low mood & suicidal ideation with physical restlessness & racing thoughts. It comes with an all encompassing sense of unease & discontent that I can't really put my finger on. I usually don't sleep or eat well during this time. One psychiatrist has called it dysphoric hypomania & suggested its a bipolar thing. A kind of mixed state, lithium did help initially to reduce the agitated symptoms but did not help my depression.

CBT is something I'm looking into as the medications I've tried so far only seem to attenuate the symptoms to a degree & general talk therapy seems to get me no where.
