Yes, mad.
It's an incredibly physical job and hugely disruptive to family life. You are not in any way adequately remunerated for staying up all night, missing birthdays, Christmas, weddings, christenings not being able to have 2 days off together, not being able to take holidays when you want to.. There is no compatible childcare so you have to have family and friends who will support your need to be absent at the most difficult bits of the day/week.
There are ways of getting more social hours and more money later down the line (Health visiting, School Nursing, Clinical Nurse Specialists, lecturing etc, but not without doing a good few years training first.
Add to all that the political mess, the brexit mess, the impact of the pandemic, the underfunding, the fact that your training will mostly be placements on wards where there's no one free to support and help you as they're too busy/stressed/crying in the sluice. And the lack of respect socially too.
I'm not always sorry I did it. But no way would I do it now in my 40s..The impact on DC would be enormous - no clubs or hobbies, missing parties and not having friends over etc. I am not physically capable of runs of night shifts when no one let's me sleep during the day. 13 hours on your feet with no break for hours , no drinks for hours, wearing a mask the whole time. And the financial side is obviously very fragile.
