It could also be meth. Same symptoms. Also if you take meth while on a ssri, very bad things happen. My ex swung at me with a metal bat in a fit of delusions....police said it was serotonin syndrome.I got out of that with only a broken foot thankfully. Also, my fiancee now had a brother, fabulous artist and meth addict who also would attack family during his delusional periods and was pretty dangerous. He perished mysteriously in a house fire five years ago...I have his art in my house, and it's clear when the real mental breakdown started occurring due to use that lasted until his death. Maybe he's schizo, maybe it's meth. Time will tell.
