What medicines are there for treating violent mood swings that happen for no reason? and for rapid frustration?

Mood swings: There are medications called "mood stabilizers" that help with this kind of problem. One example is depakote; another is lithium. For optimal treatment you should be under the care of a psychiatrist. Living with such mood swings and frustration is very difficult both for you and those close to you. Best to get treatment.

Great Question: First it's important to see a psychiatrist who can give you an accurate diagnosis for what is causing the mood swings. Once that is done, a medication can be prescribed. Counseling may also help. In addition, it would be good to see a general medical doctor, because sometimes a medical condition, like an over-active thyroid gland, can cause mood swings. Hope this answer helps.
