Sudden difficulty in reading?

[EmilyN00]

For starters, I've never (that I remember) have had difficulty reading. I'm actually a really good reader, but recently I have struggled. Words get swapped around or completely vanish from the sentence all together. (I've read 'manes' as 'names' for example, and some word changes have been more severe than that.) I've always noticed I have begun to struggle to get the right word, as I can't think of the word I want and only find myself thinking of words that don't fit. When talking to my cousin, I kept saying the word 'smart' instead of 'knowledgeable' (the topic made these two words different in meaning)
I have also been a bit sleepy this past week. I usually wake up at 7 (on my own) and get up and moving around. I've slept in till about 8 and then I lay in bed and snooze for longer, not fully waking up until 9 or later.
I'm anemic (iron deficiency) and on supplements for that. I also get low blood pressure quite often, but take no medications for it.
I have been getting headaches recently, localized to about the right/top part of my head.
