Hi Scarlett, I'm so sorry to hear your not feeling too good these days.
Do not worry about your home hun ok? it does depend on when you took your mortgage out, ie: before a certain year... and then if it's after that particular year ie:1994 then they make you wait about 9 mnths before they start helping. Your council tax will be paid so that's a money worry you dont have to think about.
They will probably make you wait about 3 mnths before your application goes through.... and they'll probably loose it 3 times cos' they like to do that... it's a real stress but stick with it and you'll be fine.
You will have to pay your interest on your mortgage until you start getting help from DWP. I basicaly starved for 3 months and that's with M.S, no sight and couldn't walk lol....
As long as you've paid your N.I and self employed taxes etc you should be fine...
