Poor memory

I probably have the worst memory of anyone I know. Well, at least of anyone I can remember. I find myself forgetting everything. I will go to the grocery store and forget what I needed to buy or go to the drugstore and forget my prescription. I think I have too much on my mind. I have started writing everything down and I mean everything. I wrote down my entire grocery list to take to the store. I wrote down the entire directv channel guide, so I could find my favorite easier. I even wrote down my cell phone number. I need to look into taking some vitamins or working on some memory tricks. When I was in school and had to remember things all the time, I was wonderful at it. However, I think the memory portion of my brain has been inactive for so long, it has forgotten how to work. I am sure once things slow down; I will have an easier time, but right now I will have to stick with my lists.
