There is nothing you can or should do treat her. It's just not your place. You can't change her or make her do anything. If SHE wants help or treatment, if SHE wants to change, then she can seek out therapy or medication or training. But this all has to come from her. If she isn't motivated or doesn't want help, then nothing will work. You can't want it enough for the both of you. This is her issue and she's the only one who can address it. And the more you push her, the worse you will make the situation. People don't usually want their spouse trying to "treat" them. It makes you like the "parent" and no one wants that in a romantic relationship that really should be an equal partnership.
