Get out of there, however you do it. I’m imagining that’s not the sort of experience you’re wanting to be having every day. If you feel current circumstance really forces you to be in this situation, then you’re not seeing all the options that really exist since they’re probably moreorless infinite. But even if you do unnecessarily restrict yourself to this one possibility, another thing you could do is change a lot of your beliefs around it and not take it personally etc. In other words if you feel you have to stay in this environment, you could use it to teach you how to deal with this kind of shit without it bothering you, a self-development project as it were. Every time you feel bad about something she says that shows you are taking it personally and processing it as a threat etc., you could work on that. Apart from that learning experience this just sounds like an unhelpful situation, so I recommend detaching and going your own way.
