Just wondering, when sufferers avoid, or ignore, or go into isolation, what is it you think about?
Those are seperate things, for me. I avoid things (like crowds of people, loud noises, etc) which doesn't have a timeframe but it also has nothing to do with another in my life. Ignoring, also different. You are speaking of isolation it seems and it would be more helpful to understand my answer if you read the stress cup anology:
The Ptsd Cup Explanation
So, what do I think about? Not loosing my shit and going postal on someone or end up on the suicidal edge and falling over. I do not think about those I am isolating from as I am too worried about my own issues and getting some control over them. To be blunt and honest.
Does it help to calm your anxieties? Or are you suffereing in silence?
Both actually. The stress cup also answers this but when that stress cup is overfilling we need to relieve some of that stress, thus we isolate. In my own experience anyway.
My sufferer blocks me or ignores me from communication. He normally comes back, but he's even more guarded and hesitant to be around me. I have been trying to create a safe place for him to come back into the relationship. But nothing is ever talked about or resolved. So we can never really move on. I feel we are stuck in this pattern
There is a vlogging couple I follow and the wife of that couple has PTSD. He gives her a large amount of 100% alone time everyday. He takes the kids, and the camera, and allows her to go into whatever room to just destress. That maybe something you can add into the relationship that may allow him to destress without the need to isolate but I think that when the stress cup is overflowing, the need to islolate will always be there. For my anyway.
And he is likely guarded because he has been fighting his own issues for that timeframe. PTSD is often times a battle. For me anyway.
How long can shutdowns last?
For me right now, months. But there is no answer to this! It can be a few mins to breath up to a few yrs or more. It depends on the person, the treatment, the set of symptoms, why they are isolating (which the reason for me changes but it can always go back to the stress cup, usually), the enviroment, the support system and any other members of that support system, etc.
And to answer a question often asked, I never advise why I isolated. The only expection to that is here on the site.
