when my memory lapses are over.

I've been suffering from obscure conditions for a long time. I have intermittent memory loss. In general, my memory is excellent, I studied well and work successfully. But! When I am under severe stress, I forget whole episodes, what I did, how and why. During this period, I am bound to lose things. Then I don't remember where and how I lost it. And if I find it, it's in very surprising places! For example, I was stressed out (thinking about problems) buying groceries. I paid for them, went outside (I don't remember), and threw the keys on the lawn. The supermarket security picked them up and told me about my behavior. And I woke up at home without the keys. Now I've lost some important documents. I don't remember anything at all, where or how. When my memory lapses are over....
