Hi, Amanda,
As somebody who considered himself a TMS success story (I'm now encountering a relapse), I can tell you what worked for me in my route out of hell last year: acceptance. Pure, unadulterated, this-pain-is-nothing-but-a-sensation acceptance. Now while you have the TMS diagnosis (which is a tremendous boon!), it is clear that your primary issue, perhaps, is confidence in your own abilities to heal: a fatalistic attitude very common among TMSers, I think. Why do you doubt your ability? We are much more powerful than we give ourselves credit for. While I might not be the go-to for advice on sustained healing at the moment, as I am going through a difficult time myself, please know that your potential is much deeper, and more vast, than the subconscious will lead you to believe.
Kick ass and take numbers.
Best,
Steve
