Hi Id
I think you may be confusing the ESA guides and the PIP guides.
In the old ESA guide, mental health was separated from physical difficulties. The two have now been combined.
There has only ever been one guide for PIP. Mental health couldn't be separated because the questions for PIP are not set out in the way the ESA questions were. Your mental health might have an impact on every one of the PIP questions.
You have your old PIP form as a guide. If you look at page 101 - 108 of the current PIP guide it will tell you how to fill out the form. That's only 7 pages - so hopefully not as daunting.
