Im in that position now sick pay has stopped and trying to get on esa. One bit of advice write down every call you make to them and what was said. They are very good at forgetting to tell you things. They forgot to tell me they need sick notes as i was giving them to work still, they stopped paying without warning. hoping its all sorted now. It is horrible going from working to not, so best of luck to you and have a great xmas.
