I think it's exactly as Arashi222 points out earlier in the thread.
I believe that while yes we struggle with somethings it is and should not be used as an excuse to just do nothing. There is always something you can do. The trick is finding your niche and sticking to what works. Now that being said I know that is hard. But honestly I hugs everyone here because here we are safe to be.
I can get very overloaded with a task. Indeed I experience this every time I go up to the board in my mathematics tutorial at St. John's. Students at St. John's are required to do math "propositions" as according to the original mathematicians, i.e., Euclid, Ptolemy, Copernicus, Newton, etc., following each step and explaining how the proposition relates to other parts of the chapter, book, or concept discussed in class. Students also have to present in Language as we translate sentences from Ancient Greek (or later for me, Middle English and French). But, the thing is, it's not a presentation. If it was a presentation, I would not be having these problems. Students are inquiring and curious and ask me questions as I present, which overwhelms me. As a matter of fact, this process of asking questions is what makes the class exciting and forces me to learn; I ask questions, in turn, whenever someone else is at the board--and whenever someone struggles at the board in these two tutorials, I help them, understanding the situation they experience.
I am encouraged again and again to examine the "whole" over the "parts." It's a hard skill to learn, especially having Asperger's. But I am certain I can learn it; I can feel the topic getting to me already even as I type this because I have such an emotional and strong connection to this struggle to see the "whole." Yet somehow the more and more I struggle to understand the "whole," I realize that the "whole" has to be painted by other people. It has to be shown to me. But for me to see it I have to deal with the anxiety that comes with Asperger's. So, the anxiety is not an excuse; I'm thinking of new ways every day to handle what I call "my bickering mind." It doesn't know any better sometimes other than to panic, to enter a state of repetitive questioning and the need for continuous assurance that comes with Asperger's. Or the continuous anxiousness that comes with being afraid and assuming that being afraid of peers remarking about my slowness to grasp the concept on the board when I am anxious and afraid of criticism. It is no excuse despite the severity of the anxiety.
In cooking I have no excuse either when I get so overwhelmed by doing many things at once. Or at work where I can tolerate only so many commands at a time in a sentence. No excuses.
That is not an excuse, that is a reason, which is what you just asked me for.
Instead, I work with them and focus on strengthening what I do have. I take breaks when I need to take breaks. I ask for things to be repeated to me, for the sentence to be broken down into simpler terms. I ask for my peers in my math class to repeat what they say and guide me through the process...to the best I possibly can while realizing that I will get better. And yes, sometimes the people I am around will act like jerks or want me to conform to "their" standards of doing things. It's annoying. So annoying. But at least I try to vocalize my needs. Most understand, but for those that don't, then it is the silence that will make them understand. When they understand, then it is no longer an excuse but a reason, "which is what you just asked me for."
