How to cope with the constant blame?

How do you cope with the constant blaming? Everything is my fault, the depressive spirals, the anxiety & rage that comes with it.

I make everything worse, I'm triggering, I'm an awful, uncaring, cruel, vile, person.

I'm burnt out. I'm am the empty cup. I don't know how much more I can give.

How do people survive this? When does is get better and back to a normal relationship? Is that just a pipe dream?
