Any ideas on auto suggestion?

Does anyone know about or experience auto suggestion as a facet of their experience?

Please could you tell me about any time you felt you were in direct control of your the nature of your own diversity?

I feel that that all I need to do is (accidentally) focus on pretty much any perceived deficit and it can either disappear to the extent it is not longer apparent, especially to myself; or, conversely, any deficit can be 'talked up' to the extent that whichever executive function / other function is so severely impaired it starts to impact my daily life. And "gods' honest truth" I really, really would prefer that some of those behaviors were never re-displayed in public.

I feel the options are: a) this really is an ASD (/MySyndrome) thing....  b) I have messed up and caused a psychosis in myself    c) yes/no/maybe/...whatever I imagine it may be: it is not.

(NB I am not sure *at all* where option c) above is sourced from but it is one of the few things that give me comfort these days)

There is a significant potentiality in which I have carelessly triggered this in myself, however I sincerely hope to find evidence for that not to be the case. 

I have only really accepted the reality that I have ASD for a few months, sort of. (I'm 41 and have suffered significant comorbidities due to the collective influence of my age, IQ and experience)
