First of all thank you for comments and offers of help. I have had a drink of gin and can appreciate you were trying to help.
However, me not doing as you say isn't because I'm dismissive of you - it's because it's unworkable.
Quite a few people have suggested 'do supply on the day of the course!' Well - the course is on the Saturday. So that's out. Even if it wasn't, supply just isn't a option for me. There's barely any around, I have no transport, and certainly do not have the money to pay for a taxi. By the time I'd paid for a taxi to the school, paid for childcare for DD and after school clubs for DSs, I'd be no better off. It would still be worth doing, except I wold lose money because the after school clubs are paid for on a half termly basis and we are scraping the bottom of the barrel to feed the kids as it is, it isn't a question of 'the money is there to spend on childcare but we're spending it on other stuff' - we don't HAVE it!
I'm sure some of you will still think I'm BU not to do supply but trust me I have tried to think every which way of how it would work.
Volunteering in the kids schools is a no-go for the same reason - no one to look after DD.
A minimum wage job would not pay for childcare during the day so has to work around DP. I worked in a restaurant over the Christmas period (October onwards) and am looking for something else but haven't as yet been successful. There just isn't a lot: anti social hours mean again transport is an issue. There is a possibility of working at an elderly residents home, I hope something comes of it.
I'm not sure what else has been suggested. I'm secondary trained by the way - History.
I understand some people mean to be kind, but would be grateful if the PMs telling me they will help would stop, as people tell me they are always successful in their applications and its making me feel even more inadequate than I already do. I'm sure I'll get my head bitten off for that but I didn't ask 'Aibu to ask you to help me get a job' so ...
The truth is, I was desperate to train as a teacher and I did so at huge cost to my family thinking it would be OK when I had work. Instead I've wrecked everything and we may lose our children's home because of me, I have to live with that. Perhaps DP is right and the course in question preys on people's misery.
