Have you actually asked for a mood stabilizer?

The two most common are lithium and lamotrigine (lamictal). Lithium can have a lot of side effects and I don't think many psychiatrists would prescribe it to someone who does not have bipolar. Lamictal is milder but has a chance of Steven Johnson syndrome which shows as a rash and could be lethal. It's a really small chance. Lamictal is also commonly prescribed for epilepsy.
