first.... huggers are so important...

And yes, I have had that sensation... many times in life.. for me something in my current life triggers that "flood" as I call of it of past feelings, sensations... and "flood" is the operative word.. cause it just takes over... and feel, feel..is what happens to me...

I try when this happens to do "grounding" techniques.. I try to recognize that it is a "flood" and that it won't last forever.. that it to will pass.. and then I try very hard to get busy with something in my life that is "routine" for me...
That eventually.. pulls me out of the past.. and puts me in the current.. in the here and now.. and the "flood" recedes..

Even though it feels like it will last forever.. it won't.. that perhaps will help to know...
