Single parent about to drop out of work-gutted and frightened

[Steakandkidney]

Hi as title suggests.
I'm really low about this.
My exH left when I was 3 months pregnant with DC4.
I had just finished my degree.
I was on benefits during the pregnancy then when the baby was 2 months old was offered a lovely job which I took (had awful PND-still do). I then had to take unpaid leave due to caring commitments of disabled son. During this time I was on income support, I still got carers allowance, housing benefit, council tax benefit and child tax credits. I was stable and able to care for the kids properly.
I went back in October. I have lost my income support, council tax and housing benefit, and carers allowance, all of which have closed. My wages are 614 pounds a month (think apprenticeship type role).

An expectation is now that I have to do evening work. I love the job, there's room for progression but I have no contact with ExH and no family. I have a 16 year old who babysits but no one to properly look after them. My DM is toxic and I recently went NC because I couldn't take it, I can imagine her sneering at me having to quit.
Basically, I'm going to have to quit aren't I. To go back on benefits on half the money I was on before because it will mean UC, I wish I'd not bothered going back but I love my job. The thought of being on benefits with nothing to do makes me want to cry. I'm clever and great at what I do, and I'm going to be trapped doing nothing because there is no proper childcare available. I'm such an idiot.
Is there any future here, what do I do?
I have always been of the 'where there's a will' school of thought but have come to realise that as a woman with children, it's bollocks.
TIA.

So couple of questions.

Can you still qualify if you work PT?
Are there any other nurses that know of an overnight CM?
Can you work 3 twelve hour shifts or 4 ten hour shifts instead of 5 eight hour shifts?
Can you qualify as a RN doing district nursing which tends to be daytime only.

After you qualify look at moving to Canada. Nurses are paid much better with good shift patterns. University for your DC will be much cheaper too.

steak Hope you are doing ok. Your story resonated with me because my mother went through the same in the early 90s, 20-odd years ago. It's so sad the NHS remains in some bizarre time warp. She specialized as a renal nurse which worked out great. She left for Canada and worked in the Toronto area before retiring from ill health. The Canadian pension she gets is very good.

One final thought is that you might want to consider contacting your MP and asking them for help with this. It is a political issue and it's amazing what MPs can help with. My mother went to Frank Field and they worked out a schedule for her that worked with her childcare responsibilities after he made some calls.

Want
It's too late for that, I've started the leaving process.
Today I dropped the kids off and went back to bed. Managed to get up later and sort some ID and stuff out because I'll need it to start again.
Have sent some emails asking about but just dead ends so far.
I keep going between absolute hopelessness and a bit of hope.
The job absolutely couldn't be any more flexible, they did what they could and have offered me good references.
I just can't see anything coming together tbh.
