I see two approaches to recovery in general, one that works and one that doesn't.
One is to pile all the corrections on top. I am A, want to be be B, therefore I must do B-A and then that will be fixed. This doesn't work. This is band-aid work, and it becomes even MORE stressful because it requires active management all the time. Math may say that "A + (B-A) = B" but the brain doesn't work that way. The other way is to accept the structure of the brain as it is, correct its instinctually-derived (but unhealthy) habits based on memory response, and have a new core within yourself that is more at ease with the world and the situations in it. From there, comfort and peace in being who you are and engaging in real life situations flows naturally without active thought. Particularly when you give the brain its time to relax and pull its own threads together under the surface. Sleep, meditation, play, all very important.
I just had this conversation with a friend yesterday...he basically said, man, I'm still hung up on this breakup from last year. I KNOW it's in the past, it's so stupid I still FEEL bad about it (emphasis mine). Here's what I told him:
The mind is an inertial entity. Temporal logic fails to apply to something that is built on memory and emotion. By that I mean, if the mind transcends the linear passage of time on a regular basis in its everyday function, why would linear temporal logic persuade it? (Somewhere in there is the basis for the phrase "lateral thinking")
I'm addressing the idea "the linear temporal logic says I should already have accepted this, but I haven't". Right tool for the job. Convincing the brain to restructure its stimulus response is not the work of linear logic.
My model of the brain has become more...it's a memory storage and retrieval tool. The memories record emotional content that is derived from the amygdala on storage, and activates the amygdala on retrieval. We have some innate responses to emotions, particularly negative ones, that are self-preserving in an instinctual sense but are socially dim-witted and pretty ill-equipped to deal with the complexity of our contemporary way of living. So the issue becomes when the emotional response of a retrieved memory invites a certain instinctual response that is self-defeating, and you get trapped in those loops, and it takes a pause button to stop mid-cycle. To go, wait, this response is self-defeating and emotionally inappropriate for the actual situation. Have to step out of the realm of being on emotional autopilot and take the challenging step of trying something new and unproven, and if that comes out more positive, it's the beginning of a new response that is healthier. That then needs to be consistently reinforced until it becomes habit.
Think it's important to look at the common threads that bind your actions not as being connected in time, or by certain situations, but instead by emotion. Then, what is the core of that emotion? And is that core a falsehood or a reality? Example: the core of my emotion of guilt and shame is the sensation I remember from being abused that I wanted to scream but couldn't get it out. My whole life, I took on my shoulders the burden of not protecting myself. But that is a falsehood. I was 3 being attacked by someone aged 40. There is no sense in being ashamed of being overpowered and defenseless then. So now when I am in the middle of feeling shame or guilt, I sense that emotion and say "ah-ha, is this an inappropriate or appropriate application of this emotion to the situation I am in?" A lot of times it's not. I can choose to do something different, like speak up instead of biting my tongue, or acknowledge my stress levels and breathe or adjust my posture to bring me back down from an anxious state. Slowly but surely, I'm tearing down a lot of my old assumptions about who I need to be and how I need to act. And developing more positive new habits along the way.
