Honestly I think it is really easy to get burnt out being a therapist and it is important for them to have a good work/life balance. Imagine spending all day helping clients and then in your spare time going online and trying to help more people. It would be exhausting.

You might be interested in Kati Morton though, she is a therapist who has a Youtube channel where she talks openly about mental health issues and answers people's questions. She seems really nice and I like her videos a lot.

EDIT:
I just noticed your username - I'm sure you understand what I mean by burnt out!
