200mg twice a day isn't common for depression. There is generally more going on in such cases
. More so for severe treatment resistant depression, depression with psychotic symptoms, or "bipolar depression".
I once had a girlfriend in college who took 200mg a day, she was weird, not very bright, yet she did well in school because she worked extraordinary hard for it. She used flash cards, the whole deal. She's a lawyer now. She claimed to have bipolar disorder at the time, a diagnosis I disagreed with. But in retrospect she probably did have bipolar disorder as her dad clearly suffered from type I bipolar disorder. My theory at the time was that her diagnosis came about by being sort of projected at her by her father. Meaning she was coached into a set of symptoms. In other words she never really felt those symptoms organically, but out of his own sickness and hyperawareness of his own disorder, sort of provoked it out of her, as if always trying to see his disease in her. Of course she very might have very well had it.
I remember staying over there one night, it was like the second time I went there. She lived at home and was i think 22 years old at the time. Her parents knew i was there. He later brought up some sleeping pills on a little dish, somehow he knew i couldn't sleep. At 3am i hear a hair dryer go on for hours, she said "oh thats just my dad".
Its funny, he kind of looked like me. But she was very attractive, tall almost my height, curly blond giant green eyes, and was one of those weird cases where she wasn't fully aware of how pretty she was. Maybe that's a side-effect of seroquel

It all fits together somehow and/or someone is hiding a few finishing pieces.
