I asked my T straight out something like this a couple weeks ago. I asked her when she wakes up in a good mood does she say to herself that she doesn't wanna go in and listen to traumatized, depressed, anxiety ridden people all day. She told me No, she doesn't say that to herself when she is in a good mood or any other mood. T's care about their clients and genuinely want to see get better, but they keep an emotional boundary and are trained to "check in" with themselves throughout the day to make sure they aren't counter-transferring and losing sight of everyone's situation
