I just don't know what to do with my life career wise?

since i was 4yrs old all i ever wanted to be was a nurse and as i got older i still had this dream but also moving into midwifery later. I studied nursing at 20 dropped out twice as i felt like a domestic servant! I recently applied for midwifery but failed three interviews (two just by missing the maths entry test by 1 and 3marks and the third i was so nervous). Im not used to failing as i've always been highly intelligent and an high academic achiever. Anyway so on one of my placements i enjoyed mental health nursing and am considering going into that route as i love psychology (i studied adult before) but also i became fascinated by watching the physiotherapists at work, im stuck between mental health nurse, physiotherapy or midwifery career??????????????? im 25 and feel like im just wasting my life and time, im giving myself headaches from all this lately
