I so feel your pain buff. I recently came across a memory that is unpleasant too I try so hard not to think about scary things things I feel might be something I dont want to remember. truth is though there are some good memories too. and I dont know that we can get where we need to be without taking the risk of looking at these things. I really hope that this memory of yours is a hugely positive, wonderful memory but if it is not then we will be here.
Either I will find a way, or I will make one.
