Hi Pewty,
Welcome to HealingWell, hope you can find some answers and support here.
The problem is, it's notoriously hard to diagnose bipolar, even for doctors. And based on what you've written, I see moodiness, but I don't see any evidence of mania. Have you done any research on what depression and mania look like? Here's a link for you:
www.nimh.nih.gov/health/publications/bipolar-disorder/symptoms.shtmlBased just on what you've given us, and remember I'm NO DOCTOR, I only see depression. You say she's had a couple of miscarriages, no sex drive, is easily frustrated/infuriated. I'd definitely take her to the doctor, but I'd be surprised if it's bipolar. I'm guessing major depression. Nonetheless, she'd definitely feel better with treatment. And don't write off those hormones so fast. Those suckers are brutal.
