Hi Iris,
If you are asking for the award to be looked at again then I need to start by just saying, as always, that an award can be reduced instead of increased as a result of a supersession.
The current and previous DLA guides on mental health may both be useful. But in essence you need to give the same information you would give in relation to a standard claim and I'm afraid repeating yourself is just part of the process.
Good luck,
Steve
