Right or Wrong?

I’ve called CH. this afternoon, although she is off the machines and off the morphine, she didn’t sound right to me… She asked me to spell something and repeated it after me making spelling mistakes or even remarks that were so not related to the topic. I’m worried about her. There’s still a drain from the brain and she still has terrible headaches. She’s tired of having to stay at the hospital because it’s boring. I can imagine it is but hopefully she will realise that she needs to rest in order to heal.
She wants to leave asap because she feels good, and was up and walking about later tonight when she called me on TH. his cellphone, asking me for my email address because she wants to send me an email… I was surprised to hear that and called her back because the line was breaking up. Her attention span is about two sentences and then she looses track and changes the subject all of a sudden or makes a remark out of the blue that has nothing to do with what we were talking about. I’m afraid to tell her, so I kept my mouth shut being in doubt whether I should’ve told her or not. I reckon TH. would’ve noticed this too, he was there when she called me…
I noticed she sounds confused, like there’s something causing a short circuit and things don’t quite add up. She is very forgetful and doesn’t remember what she said a few seconds later. Although she sounds much better than last week, I am still worried… It was good to hear her voice again and it was good to make fun and laugh out loud together like we used to do but I can’t help hearing this tiny voice in my head causing me to worry and telling me something is not right.
I so hope I’m totally wrong…
