No one deserves to be treated the way that your gf is treating you.

It's like... emotional and verbal abuse and black mail. No matter what you do, she makes it out to be that you are terrible.

Sometimes love isn't enough. You might love her, but it doesn't sound like you are getting anything at all out of the relationship. It's so completely unstable! You shouldn't be having to walk around so nervous about what she's going to blow up about next.

It sounds like you would be better off moving on from the relationship. Is that even an ok possibility for you? Like... you live together. How financially entwined are you? Would you have anywhere to go? Would it be difficult or easy to move your things?

It really sounds like if you stay with her... you need to have a good discussion on what is acceptable behaviour or not. Which is how it could be helpful to have a professional involved to help mediate.
