Which hospital in London has the best conditions for nurses?

I don't know maybe some of you can find it offensive but I have to declare, I can not keep working in nursing any more. It is not the thing I used to think and I find it very depressing and tough. I can not find energy for helping people because this work eats it all. Maybe you can advise me something... Thank you

Nursery workers play a vital role in providing care and education for young children. More than 70,000 employees are engaged in nursery work in schools, with many more employed in government-run nurseries and crèches, as well as playgroups, family centres and health centres. Opportunities in this sector exist for nursery nurses, nursery assistants and nursery managers
Nursery nurses and assistants are expected to organise, lead and supervise children’s activities. They interact with children, assist with meals and provide personal care. Managers have much more of a team-leading role and are responsible for the day-to-day running of the facility
Employees in this field generally work between 32 and 40 hours a week, which often involves early starts and sometimes Saturday work. They are required to have a CACHE certificate in child care and education, a City and Guilds Level 2 award in early years care and education or an NVQ/SVQ Level 2 in early years care and education. Salaries are in the £10,000 – 14,000 range. More senior positions, which usually require greater experience and a diploma in child care, offer around £15,000 to £20,000.
