I wonder if it is normal to feel down sometimes if you have a memory impairment

I think that if you live with a memory impairment, the symptoms can be difficult to deal with. If you are having a stretch of multiple days in a row full of symptoms, that can greatly impact your life. When that happens to me, I can become a little down and even more tired. I think that is because when I am having a lot of memory impairment symptoms, it can take much more effort for me to function. My brain has to work much harder and I think that makes me much more tired.
