Internal errors

Or how your brain tires itself.

Today miss therapist gave me the task to write about what difficulties or hindrances I have in every day life (whenever whatever stress I have), why they are so difficult and where/how they are related to my past.
Apparently this is exactly what I have problems with. And the main problem every day.
This assignment is too open for different interpretations and there are too many different ways of doing it, hence I am scared I will do it wrong, doing things wrong was never a good thing. So that gets me straight into the next conflict. I have to do this, since we agreed I would, but I don't want to do it, since I might fail getting it right. Not doing it means I can't go to next appointment since then I have to admit I didn't do it, maybe find excuses, lie about it some, which all could cause troubles. Doing it means I will be scared what reaction I will get. And the insecurity of not knowing that might outweigh the stress of not doing it.
Since I'm feeling quite okay (or decently stressfree) past weeks, I only have to handle the stress coming from this assignment, which means in the end I will just write something, go all waa to appointment, then sorta semi refuse to hand it in until I thoroughly explained it to the bone, making a total mess out of it, confusing both me and therapist and then probably am done with it, since well, therapist isn't my mother. Nor am I afraid of her and/or her reactions if I just think normally about it (which might be another problem).
Just what path of stress to choose. I semi ignore this for a week, be stressed I still have to do it, then do it last minute. Do it now, be stressed for a week I did it wrong, high probability of editing it for a week, stressed the edited parts only made it worse.

Also, does this count as proof I really really don't like changes? I started to write, then kinda noticed the trouble doing so, played bejeweled, noticed stress rise, pain in weird places, went for a nap, woke up sorta still way more tired than past weeks, still tired, just want to curl up and not think about anything. So I figured I could at least write about the process here.
