When I read stories like this, I feel so glad that I have a T that can manage 'it all'.
I remember early on in my therapy with her, I was in a psychotic state emailing back & forth one evening with her. I can't remember now what I was saying, but it felt extremely urgent back & forth.

I remember talking about it later with T and me saying I was afraid she wouldn't reply and/or that she would leave me because of what was going on. I remember her saying of course it affected her as a person, but it was part of the work.
She understands it is all about the work. My state may have been upsetting for her, but she knows it's not about her. No rupture.
I don't tell this stories to brag. I tell them so others can compare and decide whether what they've got is enough for them, or whether to look for a T that gets and understands 'THE WORK'.
