I don't think its either/or. I mean, a psychiatrist would probably (based on the shrinks I've dealt with, anyway...) pick one. There's a good bit of research that shows a high rate of trauma amongst those with "severe mental illness," especially in the "Schizophrenia" category.

From a treatment perspective...well, for me, a depression drug (Wellbutrin) at a high dose did the trick. Its not an SSRI, SNRI, or TCA. The adverse effect profile is different. Less apathy, usually no sexual side effects.

The neuroleptics/tranquilizers/antipsychotics only take you so far. Increasing the dose beyond a certain point may or may not help...it definitely increases adverse effects for a lot of people.

Sedatives--benzodiazepines, gabapentin, the new super neurontin (Lyrica), even hydroxyzine--can help with some of the problems resulting from trauma. I personally wouldn't take a benzodiazepine long term, but...that's from personal experience.

Talking treatments can help, if you can find a good counselor or therapist or psychologist. Writing has helped me, and its free, more or less. The visual arts have proven beneficial for a lot of people.

Exercise, if you can. Proper nutrition goes a long way, too. I take supplements (Orthomolecular), and those have reduced the adverse effects from my prescribed drugs (including a high dose of Abilify) down to more or less 0. I also think I get more mileage out of the drugs, and I'm calmer.

Prayer helps me. I don't consider it "therapeutic," because I believe in Jesus, and I think He really does help people.

Sorry this is happening. My personal advice would be to try to avoid self-diagnosis and categorization, if you can. The DSM and ICD are there mostly for billing purposes and also to guide treatment, which these days ((for most of us)) is focused on drugs, sometimes shock treatments, rarely operations. I find that the less I think of myself as "Bipolar I" (my current, official label) or "Schizophrenic" (the other label, from years past...), the better able I am to just...live.

I hope things get better for you.
