Losing my language skills
terrified me. To find that suddenly I couldn't remember words, remember how to spell words and I couldn't remember how to say them caused me a lot of anxiety. Well, it caused more than a lot of anxiety actually. Panic would be a better word.
I do have one suggestion for you, you might want to have your thyroid level tested. In particular if you're on lithium. Lithium can cause low thyroid and that can cause memory problems or having trouble thinking clearly.
As for what I do, like Forgive77 I just try to let what I can go. Sometimes that works.
