I tell myself I have been triggered,I am just experiencing PTSD symptoms that will pass,I need to just ride them out,etc.I usually silence my phohe,don't answer my door,lay around on the couch watching light hearted movies,soak in the tub,take naps,do things I enjoy like drawing,reading,painting,coloring in adult coloring books,meditate,listen to music,etc.I pretty much avoid the entire world for awhile,only do what's absolutely necessary,let the house,dishes and everything go.I save all my strength for myself and put all my focus on myself.
