Where memory is involved, and you seem to have difficulties in particular areas more than others, some testing could be very helpful to help you and others no what to expect, and give you an understanding of your abilities and any possible impairments. A standard psych eval could be useful, and maybe some neuropsych testing also.

Some important considerations might be whether you have always had the problems you are having now, or when they started to show up. Has it gotten worse recently? What's in your family history? Any learning problems, mental illness, dementia of any kind? Your age may be important. Also your general health status.

If any of these problems affect your work, you might be able to get the testing through vocational rehabilitation.
