Trying to remember

I am trying to remember all the things I need to tell this PhD regarding my difficulty to concentrate and confusion.  Last night I was thinking about the times I am just sitting there thinking and then start talking from the middle of my thought.  When my husband looks at me confused not knowing what I am talking about I have a hard time pulling my thoughts together to explain.  It's like I am just rambling without any sense and can't seem to make sense out of it to tell him.  Sometimes I just say forget it.
