Welcome to the club. I’d definitely take Tim’s approach re arguing for a pump – can you ask if you can borrow a CGM from your clinic for a week or two and hopefully use the data from that to show you’re experiencing significant swings in BG or particular problems a pump would solve?
Also, I found I was being a bit too stoic about the whole thing, just getting on with it and not whinging. I started keeping a list of how diabetes was impacting my life and work and how a pump would make a difference to that.
My top tips on fighting for funding are here – https://www.shootuporputup.co.uk/2009/07/show-me-the-money/ –
but there’s no magic answer I’m afraid. I’ve always suspected I got my funding by being such a pain in the arse that they eventually gave in for some peace and quiet
