Sounds like you need either a break (vacation, visit with friends, etc) or you need to find a way to get her out of your house. You have a right to a happy life, ya know. There are no rules that say we must tolerate abuse on a constant basis, even if the person we love is schizophrenic.

Check out your options. You don't have to live like this even if you believe that you do have to live like this. It can be hard to push her out but an alternative way to view this is that you are enabling her to learn from others by placing her in an environment in which she will have the guidance she needs, ie, like in a group home for those like her that are supervised by people with some training in schizophrenia and who have the luxury of emotional distance (ie, they aren't related and they get to go home at the end of their shifts...)

My heart goes out to you, dear.
