We do occasionally see this happen, you can request a two-week extension for the return date of the PIP form but there isn't one for ESA so I would concentrate on that form first.
Have a look at our ESA and PIP guides for assistance with completing the forms.
www.benefitsandwork.co.uk/help-for-claimants/esa1 and
www.benefitsandwork.co.uk/help-for-claimants/pip Do an internet search for "welfare advice" with your postcode, town or county for support with the forms, you can also try any charities that specialise in your conditions.
If you have any specific questions then please reply to this post and we will do our best to help.
