I experience similar difficulties with memory and other aspects of cognition. It's gotten to the point where I can barely cope day to day. The number of tasks I am unable to effectively attend to has grown ever greater as one problem precipitates and potentiates another until my capacity to cope with the continued failure to arrive at a solution to these problems triggers suicidal ideation - just now I had an additional thought and part of a sentence formed, but I was unable to hold it in memory strongly enough to recall any aspect of what that thought was. Sometimes I can, more often I cannot.

It takes ages to learn new information and using that information is almost involuntary, as if I do little more than output data with little to no willful intent; no plot or method of discourse, simply an ad-hoc improv whose direction is determined by something I don't quite understand, let alone exert conscious control over. I do not 'know' things, just contain them like a repository. It's like I'm not even real, just there, with pre-formed responses; when I'm talking with others I usually cannot remember what I or they said not but thirty seconds ago, just random bits of information which sometimes can be used to inform me of what is being discussed.
