I go in cycles from coping well to the shaking and jumping at everything.

I've developed a few coping skills - and CBT helped a great deal.

I planned things out. I did for example my groceries at an all night market. I would sit with my back against the wall anytime I went out. If possible I had people come over rather than go out. I stuck to a routine. Most of all though I am lucky to have someone understanding around whom I feel safer.
