On words and facility with language

My sister-in-law lives in Las Vegas. She housed hubby when he was there after MIL's disappearance and reappearance. She's been living with chronic leg and back pain for years, is on disability, and hubby says that he sees me going through some of the same things he saw with SIL. For example, I lose words. I grope and grope for the right word. SIL warned hubby that I would be going through this. He's more comfortable than I am with the strange difficulty speaking and loss of words. I hope it isn't going to be like this forever. I pride myself on my ability to speak and write well and intelligently.

I fear it will.
