You’re a member of the club! My dizziness is exactly as you describe, and I can’t predict when it’ll happen. I lie in bed and turn my head and I get dizzy. Sometimes when I’m out and about, I stumble and worry that people will assume I’m drunk. PT told me to move my eyes first, gradually, in increments as I turn my head. Sometimes I remember.
The word-finding problems drive me nuts. What my speech therapist told me was, don’t panic, think of things that it’s associated with, or how it’s used and don’t worry, you’ll get it, or the person you’re with will come up with it. I’ve used online search sometimes. The worst thing is people saying “well, that’s just getting older”: I was in the hospital, received pt and speech therapy, and also have a card in my wallet saying I have a brain injury. So, no, it’s not just getting older.
