I have found that what gets me through trauma and frustration are internal resources.
Whether my difficulties are the result of my internal or external situation, my internal resources are what enable me to get through and around them.
They are on the one hand the little light that stays on when everything switches off (the little light that is the reason why everything else keeps going when it can't - the reason for doing it, and the reason for being able to do it) and on the other hand the reasoning ability that is the sum total of my previous experiences.
Life is a series of decisions, big and small, and it's only with age and experience that one comes to see that each decision builds on the ones that preceded it. Many people who lash out at others when they are frustrated do so because they don't trust their own decisions, they may not even be aware of making them. They only notice the wave that carries them along, they don't notice their own options, much less choices, when dealing with it.
Since there are many people here with many decades of experience dealing with trauma and frustration (and many others who have fewer decades of experience dealing with them), I am curious what other people have noticed while learning how to cope.
For me, simplification and instinct make a grid and I can move along it well enough to get me through life even when I can't move in the world around me. To me that is key.
What internal resources have other people developed and learnt to rely on?
This relates to being autistic, and to life in general.
