Have a look, if you will, at the above diagram. Tracey found it here and I have to say, it's perfect for describing what has happened to me since that first day.
This image shows the very part of my brain affected by the tumour and the seizures related to it. I am far from an expert on the anatomy of the brain, but I do have an idea how this relates to my situation. It also makes me aware of how unique each case is while having characteristics in common with others, and how right my instinct was not to try to talk about these things till I had some confidence at least that I knew a bit about it - enough to relate to my experience.
My additions to this diagram are very crude and not exactly to scale. I could do better if I had the use of my right hand when using Photoshop, but it will give you an idea at least. Below is where the tumour was located when I first became aware of it. It is in the left side of the brain so we are talking about how it has affected the right side of my body.
