Hello Lucky_Wishbone: The Skeezyks has struggled with depression & anxiety pretty-much his whole life. Now, as he's getting older, he finds that his memory is suffering. It's hard to say if it's the lifetime of depression & anxiety that's causing it or simply getting older... maybe both. But the things you mention are frequent occurrences for him.

Personally I would say that not remembering how you ended up on the floor during a fall is not at all unusual. These sorts of things tend to happen so quickly & unexpectedly that one often can't recall how it occurred. Hope you're recuperating well...
