Hey OP: have you posted before, the back ground sounds fmailiar.
I am a nurse, I now work in nurse recruitment (finding jobs for nurses). You have done really really well, and are on the home straight. You have loads of opportunities once you qualify not just in the clinical setting.
My advice, find a job that consolidates your degree for 1 year max. Then look at alternative options to the NHS/ private sector.
You have sales rep, research jobs, teaching, online tutoring, jobs for assesing patients ability to return to work etc. The opportunities for you are endless, and don't necessarily mean you have to work in a Psychiatric unit.
One great role you could do, is re train in aesthetics. You can then work for yourself. It costs a little bit to do the course, but you could be your own boss.
About your DD that is hearing voices etc, how old is she? Might just be part of her developement. About the DD that is overwieght, does school have any input or have you got advice form your practice nurse?
Chin up, you are very nearly there.
