There is a specific system that allows recall and processing of words. I have suffered from word issues for decades. But, I have been able to maintain high levels of math processing. I have great recall in some areas but horrible recall in other areas.

You are confusing me. You mention word finding and such then flip to leaning against a wall. Word finding issues due to injury have no connection to whatever short term sensations/symptoms you manifest from leaning against a wall. Injury caused word finding problems tend to be chronic. Anxiety caused word finding will increase as anxiety increases and decrease as anxiety decreases and focus increases.

If you want to understand you own issues, you should see if you can get a Neuro Psych Assessment done. Then, you will have information you can use to move forward with your life. Until then, you will likely continue to spin with your anxiety about "what if this" and "what if that."
