I know you know this, but your T is being a good T by not focusing on her issues and you have no reason to feel guilty for not providing support.
A couple of months ago my T had to rearrange due to a funeral. It was someone close, I could tell. We focused on what missing a session meant to me, not on his sadness. It was ok because I know he can take care of himself.
It's a weird relationship in the grand scheme of things, but that imbalance is exactly why therapy is helpful.
Sorry for rambling on, but I wanted to say you're not a monster!
