MH and Unfamiliar Journeys

Not really a question as such, more........ confusion!

I had my last Pip review in 2018 - AFTER the court cases about 'overwhelming psychological distress, and safety' when undertaking journeys. So I was convinced I would be awarded the mobility element as I had been successful at tribunal 2 years earlier.
However - bizarrely - I got 0 points, even though the assessor recorded some of the difficulties I have.

At that time I was unable to take it further because I did not feel well enough, and I was going through a divorce and could not risk more stress, nor the possibility of losing my daily living award.

Now in 2021 my Pip review is currently in the hands of the DWP (lap of the Gods !!!!).
I did not mention any of the above, but just tried to state my case and difficulties as clearly as I could.

I am now wondering if I should have made reference to my 2018 review - and explained why I had not appealed, and also ask why they did not review my case?

I realise I probably need to wait for my result/assessment and result - before I can do more, or before you can provide advice. I am just concerned that my 'inaction' will be held against me.

I would be most grateful for ANY thoughts. Thank you

Thank you - what a helpful reply.
I am unsure whether to write what you suggested, now, or wait until after I have an assessment.

Hi Walker, sorry to hear how life made you too fragile to fight before. But now you have support from here. Still not going to be easy but much more do-able I hope. My tip is this. Just as Catherine says write in now to make sure they look at the Tribunal decision not their own last nasty one, be ready to do this: Once you have your phone assessment [masses in the Guide about that], call in two days after and politely request the assessment report [unless you live in N. Ireland]. If refused, say thanks, hang up, and try again till one agrees.
Once you get the report [PA4 it's called], go through it with highlighters marking mistakes/twisted bits and those where you consider you should get more points than he/she suggests. Then, like now, you can write in before anything else happens, to put them coldly straight referring to documents in your evidence.
By the way my very experienced friend says they always knock people back after they won at Tribunal the previous time, sounds like that is exactly what they did to you before. So they have 'saved the country' a few bob at your expense/suffering: don't let them get away with it again!
Best wishes,
Denby

Just trying to write my letter - should I include briefly the arguments I WOULD have used in 2018, if I had taken it further?
Or should I leave all that detail for later, when (if !!!!) I have to ask for an MR?
