I have two brain patterns, one relaxed, one alert non-relaxed(stress).
The relaxed pattern is expressive and relaxed.
The alert non-relaxed one is stress and anxiety.
My brain jumps into alert, fixation mode, non-relaxed in social environments. A couple of examples to describe what it feels like.,,,,,,,, say you are going to school and the school bully is waiting for you. You can not eat, think or move,, that is what happens to me. Another example is my brothers dog moving about, jumping up on me and sitting next to me staring and begging with its eyes.
When the alert vigilant brain switches on, my tension and stress increases until the trigger is gone. ! But I can't go about removing myself from the triggers because I would be living in a cave. The triggers are mostly social aka people and dealing with people I don't feel comfortable with, strangers, state employees, neighbours, anyone that has a power over me but not a true relationship of communication. Thats the world too me by the way ! 
I can't physically or cognitively move(freeze up with stress) until they go away.. ideally die off if possible. I get this with fixed appointments as well.
any advice
