Hi Charchar
I'm sorry this has happened. Don't be afraid to ring and ask. As you have only just sent it, I hope they will be happy to send you a copy. Explain that you cannot remember what you said because of your condition. Whatever they say, make sure that you keep a record - so if the form does not arrive in time for the assessment, you raised this as an issue.
