Detachment?

I guess, no surprise here, I'm having trouble finding a way to detach. It seems there are people out there who are hell bent to keep the wounds open and festering. I am not sure whether attacking head on or retreat is the best option. I suppose at one point I was kind of a part of the problem as far as keeping the drama "alive." I'm past that now. I want it to stop. My life is good and I want to get on with it without this constant past trying to invade my present and future. I suppose it would be helpful to know WHO was filtering information around but I don't and that makes it a bit more complicated to address. Perhaps I will finally get to the point where I just switch off the pc, cutting off their main source in which to attack me.
