No, there is no official diagnosis for slapping oneself; although it occurs quite often. Typically, this is part of an inability to regulate, control, and effectively express anger or frustration, so the best form of treatment is to learn how to deal with frustration and anger through counseling.
Usually, when a person become frustrated or angry, they have thoughts, and feelings about it, and then do something (behavior) but with a hitter, they become overwhelmed because they weren't taught to properly deal with situations - they can't think things through effectively.
In counseling, someone comes in and tells about a frustrating situation. We talk them through it, pointing out triggers, other options and finding new ways of coping. Eventually, people learn new skills and don't hit themselves.
How else can I help?
You can't be forced to take medication. You also can't be institutionalized for this; to be held on a 5150, or under the Baker Act - you would have to be a danger to youself or others. Hitting youself may hurt, but it's along the same lines as cutting - it's not good, but it's not suicidal (the criteria for a 5150).
I think you *should* talk to her about it because if you had better coping skills, you wouldn't do this -- and being honest with her will give her the information she needs to help you (does that make sense). In other words- she can't give you the correct tools if she doesn't know what you are doing.
Remember, we, as therapists are non-judgemental - we really do want to help.
What you need for her to do... is walk you through it, and discuss what the triggers to the slapping are. Once you know the triggers, you can work through them. Then, you can find new ways of dealing with the triggers - and then you won't feel you need to hurt yourself - but will have good tools to do things differently.
