I wouldn't rush ; you could always do a HNC and HND then skip into 2nd or 3rd yr of a course you want to study; don't rush into a course just so u can get into university.
Remember you will leave with a tone of student debt and need to get a career afterwards. You want to be physical health not mentlal health ; so you would turn down the chance of Mental health Nursing for Podiatry ,Radiography. Think about this Mental health Nurses earn 40k plus a yr and can also work agency were they are paid from £400-800 a shift . Good luck even finding a job in podiatry and radiography, you would prob need to relocate.
Personal I would pick general Nursing/ disability, peds or Mental health Nursing. Occupational therapy/physiotherapy would be my next choice, you won't earn as much money as Nursing however the lifestyle would be better.
Optometry is also a good one as u can work for big private companies like specsaver ans earn a good wage with job security. Avoid podiatry; you will regret your choice within a yr and end up in someone's small private clinic cutting toe nails .
