Sorry to hear you are suffering so much. Have you tried any Atypical Anti-psychotics? When I am mixed or manic I find Olazapine (Zyprexa) or Quetiapine (Seroquel) help a bit to give me at least several hours of decent sleep, if not more. Depression is hell too. It will pass (I am trying so hard to remind myself of this at the moment). Hang in there.
