Leaving Occupational Therapy profession advice

Hi guys,

First time poster here. I would hugely appreciate any advice with my issue. Basically I'm a 29 year old male who qualified as an occupational therapist two years ago. Unfortunately I'm very unhappy in my job and I've become a bit disillusioned by it all to be honest.
I always wanted to work in healthcare and OT initially seemed to be a very attractive career option but the more the years rolled by and the deeper I got into the course I came to realisation that it's not what I expected it to be, this was further confirmed to me once I started working.
At the moment nursing seems like a very attractive alternative career option for me and I would be willing to go back and retrain. Has anyone here ever made similar career changes and if so how did you go about it? I know of people who studied medicine following OT, is anyone aware of at a similar graduate entry for nursing too?
Many thanks for all your advice.
