I can't see why your IVA would need to be extended due to a low dividend. I have seen this happen occasionally, but it rarely is the norm in my experience.
Good luck littlefi, I will be thinking of you on 6th as it was my parents wedding anniversary (I say was, as my mum is sadly no longer with me)
I am sure you will be fine, yes the next couple of weeks will drag but if you keep yourself busy it will soon be here, easy for me to say now I am through the other side I know but believe me, it's worth waiting for xx
