Let me know your progress. I want to additionally say something to explain some terms. For example, I tell myself: 'I can't'. If I engage to 'I can't' by saying: 'Of course I can', then I"m engaging to content VS If I tell myself: 'don't say I can't', then I'm still reacting yes, but I'm not engaging in the content. This is the metacognitive viewpoint, where one distances himself from overthinking. Distancing oneself leads to a viewpoint of less stressing, less emotion, less overthinking and less engaging. If I overthink: 'I can't move my tongue to unblock' vs 'I can't unblock in a feared situation' then the former is from a root perspective, whereas the latter is from a non-root perspective.
