I have wrestled with speech issues (aphasia, apraxia, stuttering) since my TBI. Therapy really helped. The pathologist spent a lot of time working on my attention span and concentration. If I can focus, my speech improves. So, I'd say, get yourself accessed by a professional.

To be honest, I will never understand why people wonder if their deficits are a product of PCS or anxiety. Anxiety is a symptom of PCS. When you try and separate them, it's like saying, incorrectly, that some deficits aren't legitimate. I believe it's more accurate to remember that, we have anxiety because we have PCS, not PCS because we have anxiety.

Treating anxiety as a symptom, rather than a cause of PCS can help free patients from misplaced guilt and allow them to confront it without shame. TBI patients are no more at fault for their anxiety than they are for difficulties with convergence, tinnitus, lose of sense of smell, etc..., etc...,
