Do my meds need to be increased?

I am on 100mg of an antidepressant (fluvoxamine) and 50mg of an antipsychotic (amisulpride). This has seemed to work for quite a while, but i have noticed in my internal thoughts some very negative things. I have been experiencing strong feelings of rage, hatred and disgust towards people i feel have wronged me in the past. I obsess about this for hours each day. I feel very slighted and mistreated. I fantasise about verbal abusing these people and offending them (ie. Urinating on them, telling them i will rape them, eat their flesh, skin them etc. NOTE - i have no intention of doing these things, i just fantasise about scaring and offending them). I act out conversations with them where i insult them and verbally attack them. I seem to be consumed with rage and hatred and am unsure if this is a biochemical thing, or psychological therapy would be better to deal with this.

Sounds to me like you need to be on a mood stabilizer. You could be hypomanic from the symptoms you describe. This could be exacerbated by the antidepressant you're on.
