I have schizzoaffective disorder and i'm very lethargic and un motivated and bit depressed, what's he best antidepressant (i'm on lamictal and abilify (aripiprazole)?

Often: Often antidepressants are not used for bipolar disorder. I would probably try to optimize the lamictal and ability dose and would consider adding in a second mood stabilizer. In the meantime - talking therapy is very important.

Schizoaffective : If you are not comfortable or unsure about the medication your Doctor prescribed then it is advisable to get a second opinion from a Psychiatrist after you have had a complete physical exam by your Primary Care Physician to rule out any underlying illness. A Clinical Psychologist can also help you with psychotherapy.
