What I'm scared he'd say:
MBM17, It's been nice, but this is the end. I'm done. I don't really care. You think you're such a big deal. You think you're suffering. You agonize about all these "big emotions" you talk about. You talk about all the things you "can't say" or are "too afraid to say" and you won't tell them to me. Get over it already. You think you've had trauma with past therapists and you keep whining about it.
You're too attached. You're care too much, and that's inappropriate.
You're manipulative and a bad person and a drain on everyone around you.
Meh, I'm done with all of it.
I don't care to keep doing this, so see ya later. Have a nice life. I have better things to do with my time.

What he'd probably really say:
MBM17, I'm on your team. I've told you that. I'm still here, and you won't be too much. It's okay that you don't believe that yet. You will. We're stable.

Because that's what he really says.
