Need some encouragement, and any other support vectors

I am in a really rough spot. Life this year has been so difficult that i have almost died due to refeeding as i was unable to feed myself, which doing so has subsequentially put me in debt (food deliveries) and an even more fragile state. In which i also got a chest infection that sent me into hospital. As i am recovering from refeeding the dreaded PIP review comes in. Last time this happend it almost killed me because of how bad it tanked my mental health, but there is even more this time to contend with.

I know i can do it. After all, even with all the thinking problems and memory problems i have, from a purely logical point of view i have the information. But i can't even look at the form. I freeze when i try to write my firstname on it. Just having it anywhere within my cone of vision is enough to cause problems. But as i am typing this i am sitting here shaking.

I can't convey information well, and i am forgetful, so i can't have someone else fill it in for me. I can't delay the review long enough to get into a better spot (I have been told they only extend the deadline by 2 weeks)

I have been filling it out on the computer but i can't do it for any good length of time. It will takes ages and i already foresee forgetfulness loops where i spend most of my time in a session reading what i already wrote because i forgot, so i don't repeat myself and to make sure i have included all information, then i am actually spending time writing information.

Any encouragement especially considering how lonely it has been this year too in a dark room, and any potential points of help i can lean on to try and get through this i would greatly appreciate you making me aware. I have spoken to citizens advice recently who made me aware of an email thing i still need to investigate. Of the people i do have around me, they can in no way relate to how difficult this process is, even without the additional factors.

Thank you in advance
