Jobs in the Mental Health profession?

Hello, I’m 18 and I live in the UK and for the last 6 months I’ve been thinking about working in the Mental Health field.
I was just hoping that someone could explain which Jobs are available and what I would need too do in order to do those jobs academically.
I’ve tried looking things up on the Internet and all it did was confuse me.
When reading up I did find something about psychiatric occupational therapy and that sounded like a Job I would love so if someone could explain that too it would be much appreciated.
