Regarding whether anxiety is a form of TMS, I have experienced panic attacks so bad that, had there been an option at the moment to choose dying, I would have taken it. Countless people have experienced and described the same. For myself, I do not believe for a minute that these somehow are a distraction from deeper negative emotions created by the brain or mind or what have you, in the same way that back pain and other somatic symptoms might be. Just my opinion and yes I am well aware of what certain books say, I've read them too.
I couldn't have said it any better. Thank you.
