Indeed, I totally comprehend your anxiety and mental health examination reluctance at this point in time in reference to the SSA SSDI process albeit please continue to remain focus and positively proactive!
From my experiences with the SSA SSDI process, I recall my wife assembling all of my prescription medications in which were hand carried to the SSA sponsored mental health examination; maybe you should do the same in my opinion in addition to the MEB NARSUM + DoVA disability findings documentation.
For me, more specifically in reference to the SSA consultant mental health examination, an Interpretive Report of Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV) test was performed due to my constant complains about memory loss and loss of consciousness concerns.
As such, the WAIS-IV test revealed a clear function on a severely regressed level as compared to significantly higher previous levels of cognitive functioning. My SSA consultant was simply great throughout the entire mental health examination albeit please remember that his/her observation of you begins upon their visual confirmation.
Naturally, be honest and sincere with your verbal responses when asked questions by the SSA consultant mental health examiner. At least for me, I know it was a challenge to express my medical conditions symptomatology to a total stranger but I would offer to highly concentrate on the overall objective to receive the "disabled" SSA SSDI determination for sure!
Thus, I quite often comment that "possessing well-informed knowledge is truly a powerful equalizer."
Best Wishes!
