I totally don't think this us personal at all.
When I worked in rescue it took ALOT for me not to take my work home. And sometimes I did literally, like hand feeding new born raccoons every two hours.

I was extremely invested in my work and it took very little to remind me of all the animals I had that were my responsibility.

When I went on holiday, one tiny text message asking where the tack room keys were could send me into a spiral of thinking "I knew I shouldn't have gone away, I knew something awful would happen, I knew they wouldn't cope. Etc etc."
Even though we had plans for every eventuality. Then I would spend the rest of the holiday ruining for my partner and kids by checking my phone and email every 10 mins.

It wasn't about the one person who called or tested it was about the cascade of worry and stress I would put on myself because I feLt I wasn't doing my job properly.

But I needed those breaks, animal rescue is hard heartbreaking and often unappreciated.After 8 months back to back I needed 2 weeks with my kid and fella.

I imagine therapy often feels the same, (not from you OP, I just mean in general.) I mean I imagine it's hard not to take it home, to never really feel you can let people go.

I hope the rest of your appointments aren't too stressful, just be gentle with yourself.
